Hey @montana_citrus2021!
I’m not sure I understand, you want to allow users to call a specific command only once and then deny the following calls from that user, have I got that right?
What should be the command’s response upon the first call from an user?
And do you want an error message to be displayed if the user already used the command (if so, anything specific?), or do you want it to fail silently?
Those are questions I shouldn’t have to ask: the posting guidelines ask to be specific.
