Bluetooth visibility

[adaorcpp]

Hello,
I have a ZenFone6 with Android 10. I just realized I cannot control the bluetooth visibility of my phone. I noticed that my phone is only visible if I'm currently in the bluetooth page and the screen is on.
This is a problem for me, I often use an app which confirms my physical location by bluetooth visibility, and this is obviously not working now.
Does anyone know how to change this behavior? Is there a setting for this?
Best regards,
Tamás

The standard behavior of Android does not suit you, maybe you should change your described detection method.
