Question How to have full-screen notifications for any app?

[Slapow]

I would like to know if/how to have full-screen notifications for any application. I specifically want full-screen notifications for tasks, so that when my reminder goes off, the whole screen will be covered by that one notification and its text in the alarm/phone call format. Any help? I am using a Samsung S20 FE 5G One UI 5.1
