Can't setup Fibaro Button on Homey 2023

Strangely, after each attempt it seems that Homey has created an ‘Unknown Node’ which is shown on the Developer Tool.

This indicates that something has gone wrong with the inclusion process. Remove the “Unknown Nodes” in DevTools (do you know how this works?), perform a PTP, then let Homey “organize” itself for at least 15-30 minutes and then try to include the Button again.
