How to mirror android screen/app to a screen programatically?

I am developing an android application and I'm trying to implement a button which initiates a screen mirror to a selected device.
I want it to be as straigth forward as possible, but the best i've been able to do is have it open the cast settings on the Settings app, which isn't a proper solution. It would be ideal to start screen mirroring with a single click.
Problem is i've tried using Googles Cast SDK but that only allows me to build custom HTML cast receivers, which isn't what I want, I just need a screen mirror from the android device to a screen/TV.
Is there any Android module/API that would allow me to do this with a single click, even if I have to use a Chromecast/Miracast device connected to the screen?

No, sorry, this is not an option AFAIK.
At least part of this is privacy/security. You seem to want to be able to start screen mirroring purely from app code ("I'm trying to implement a button", "allow me to do this with a single click"). Your button is the "single click", and so you really want to be able to do this without user involvement at all (since there is nothing forcing that button to exist). Showing the contents of the screen on another screen that might be visible to lots of people is the sort of thing that users need to approve, which is why additional clicks will be required.
In addition, there may be more than one target for screen mirroring within range, and the user needs to be able to choose which one to use, if any.
Combine all that with limited support for wireless displays across the various Android device manufacturers, and there really isn't anything here for what you want.

Is there any Android app that can detect particular text on screen and click on it automatically?

I want a app that can read text on my screen and click on the text which I can pre-define in the app. App mostly capable to identify multiple texts and if anyone of them present on screen then click on that region.

Yes.
Macrodroid.
Use the Device action -> UI interaction -> Click -> Specific text
Option in the macro and it'll click that word on the screen
👍🏻

You can't. Android doesn't have APIs for screen scraping because its a huge security hole- you could use it to grab passwords, banking info, etc. Definitely not possible without a rooted device, probably not possible even with root without a lot of work (you could maybe on a rooted device grab it right from the screen data, but then you'd have to do image processing to find the actual text).

You can do something like this,
1.From the HOME screen, tap on APPS.
2. From the APPS screen, tap on the AUTO-START MANAGER icon.
3.You will first see the DOWNLOADED apps field you can toggle apps to ALLOW or DENY with a tap in this field.
Choose the APPS accordingly to your preference to which you want to start up on first boot which also gives it full start up privilege access in RAM on the OS level.
4.Tapping on the PRELOADED option will show the PRELOADED apps. Choose with you want to toggle privileges by tapping on the applicable app to ALLOW or DENY start-up access in the OS.
5.Finally, tapping on ADVANCE options/settings (The three dots on the upper right hand corner) will toggle advance selections for the AUTO-START MANAGER app. Selections to choose are - SORT BY, SHOW ALL APPS, ENABLE NOTIFICATIONS, RESTORE TO INITIAL CONFIGURATION, NOTICE, FEEDBACK & HELP.
