The plugin doesn't work

[FilippovL]

This plugin doesn't work on Revit 2021. After copying WorksetByElement.addin and WorksetByElement.dll to the plugins folder, the 'WorkSetByElements' button appears on the ribbon in the external tools section, but when the button is clicked, nothing happens. No windows appear

Hey thanks for the heads up. Honestly after so long I've forgotten about this but according to the gif on the readme it needs to select an object after clicking the command button.

Right after executing the command, Revit should change to selection mode. Let me know if this helps.
