Android Screen Recorder App bug fix

Hello. I have the Screen Recorder application code for Android. A few changes need to be made to the application. I will write what needs to be done below.
1) Screen recording sound is not recorded in new versions such as Android 13, 14. There may be an error in the microphone or audio permission. This permission needs to be updated.
2) In the previous version of the application, when you pressed the screen record, a window called Remove Watermark would automatically open. When the user watched a rewarded ad, the watermark in the screen recording was removed. You can add this feature by looking at the previous version. I can also send you the code of the previous version.
3) When the record button in the main menu of the application is pressed, the screen is recorded. However, when the recording is started from another floating button that appears on the screen, the screen recording starts but the video is not recorded. This error is present in all Android versions. Can you fix the error in the floating button?
4) If there is a section in the application where an Admob interstitial ad unit will be added, can you add a new interstitial ad in accordance with the policies?
