URGENT need help making NANO 33 BLE act as Central for BLE camera shutter remote

I need help in making the Nano 33 BLE act as a BLE Central to receive button presses from BLE camera shutter remote fobs, which are usually used with smartphone camera apps. I've been fighting with this for a month now and cannot figure out how to adapt example codes to respond to one of these fobs. And there seems to be no information on the internet where anyone else has tried to do this.

So, what did you learn so far? Did you find some datasheets, write some code, got some debug results ... ???
