MIDI learn not working on plugins with Launch Control XL

I just got a Novation Launch Control XL and just checking it’s features.
I enabled the controller in Edit > Preferences > Input Devices > Controller. I enabled Incoming and Outgoing MIDI for the controller (Launch Control XL 4:(capture_0) Launch Control XL Launch Contro).

In Ardour itself this works perfectly, out of the box.
Now I wanted to program the User Template to my custom needs and wanted to control plugins.
I took the LSP Parametric EQ x8 as my first test because it has 8 bands which perfectly matches the 8 control channels of the LC XL.
I opend the plugin in “generic controls” mode and now wanted to CTRL+mmb on a parameter to go into MIDI learn, but nothings happening.
And to reassure myself, I tested this also on Ardour nativ controls like mixer faders. CTRL+mmb on a parameter simply does nothing on my system.

How is this MIDI learn working? Do I have to enable it anywhere? Using Ardour 8.6 btw.

EDIT:
Ah, I got this. I had to enable “Generic MIDI” alongside the Launch Control XL preset and then enable Feedback in the protocol settings.
It’s working now but unfortunatelly I found that this is not working for every plugin instance, only the one that the control was bound on. So this way controlling plugins with the LC XL is rather pointless. Sad but it is what it is.
Nevermind
