Is there any foss applock which can trigger my device's lock option to unlock an app...?

1

I would like to know if there is any app which can trigger my device’s lock, as in me having to type in my phone’s password or use biometric to unlock the app.

I have notice ente auth triggering my device lock whenever I open their app. It would be great if there is an app locker which can do it.

Feel free to suggest if you guys have any other nice app lockers which are FOSS

Maybe Amarok.

I installed Pineapple Lock Screen a few days ago with a shortcut on the home screen for instant one tap locking. It works well.
