Is there an alternative to Bouncer- Temporary app permissions? I'm really paranoid about my privacy idk why. Recently I installed Whatsapp Aero which is super cool but unfortunately its developer is expert in making spyware apps too. I found this Bouncer app which provides permissions temporarily. But this app is paid and not open source again. I tried shelter app to isolate it but due to the dual app feature in my phone i can't a add work profile. Can anyone suggest me how can i monitor what the app does in background OR make an script which grants and revokes permissions through adb OR any alternative to Bouncer? I'm gonna buy the bounce app if i'm outta options. The developer deserves it :)
P.S.  My device is not rooted.
I suggest using  Android Mobile Device Hardening which:

list installed apps and their dangerous permissions
revoke dangerous permissions for all Apps
list applications that are device admin
