Setup wifi hotspot

I’ve tried going through network manager, the osmc gui, connman to no avail.
I have a decent amount of knowledge of the terminal and raspberrypi and the similar but not exactly in this area.

Which Wifi device are you using? Is the driver supporting tethering?

How would I find that out exactly?

Which dongle are you using? Are you using the Pi built in one or an external one?

Built in

Hotspot support is missing with the 4.19 kernel
