How to remove device track points from Nextcloud Maps

I opened Nextcloud Maps on my mobile Firefox and it asked for my geolocation. I accepted and now I have an entry of my location from Phone (Firefox/Android).

The problem is, that I already track my location using PhoneTrack hoooked up to the Nextcloud log and I see it as SM-G975F (PhoneTrack/Android). I don’t want to have both. I already disallowed geolocation in Firefox, but the lone entry is still there. I know that I can hide it, but it’s annoying that it’s still there.

Is there a way to remove any traces of it?

I have the same question. I need the ability to remove Tracks and Devices I added as they become unneeded.
