Delete all Assists button

Thank you for your help.
We have a large number of unnecessary bots left on the AI Grid bot management screen.

Since the number does not decrease by deleting them individually (X button) and we cannot find a way to delete them all at once, we would like to ask the management to "delete all" unneeded BOTs at once.

Target: All unused BOTs in the AI Grid

Thank you very much for your cooperation.
