Devonthink Pro 3.8.6 and BetterSnapTool

Hello there,
it appears that BetterSnapTool does not work properly with Devonthink Pro 3.8.6. To be more precise, it does not "snap" when dragging the window to the snapping areas. Only the "Change Window/Size" menu in the menu bar performs that function. Unfortunately this is annoying.
FYI BetterSnapTool is "ticked" inside System Preferences under Privacy>Screen access/recording.
Thanks for your help.
I am using MacOS Monterey 16.0

Hello! Can Andreas Hegenberg give me a hint how to solve this problem?
Thanks!
