PS4 controller peer Bluetooth connect?

Moin people have my controller with PC via ds4 app today. Everything went well, but my controller is not displayed in the ds4 app although my controller is connected to the pc, but as soon as I do it with a cable it works and without a cable it doesn't work I would be very nice if someone could help

I think you need an adapter n you want to connect to your pc or your pc has bluethoot itself then you have to activate your controller and then connect your pc to it

I already have everything but it is not displayed in the ds4 app
