Hey @DevilsKitchen hope all is good. Welcome to the community.

You have to run the trigger while you are pasting the URL on the slack integration page.

how can i run ? while they are not connecting. without connecting how can i do this?

You first configure the credentials, then you need to connect the integration to n8n with a webhook, at this point you can run the slack trigger already. So you run it, you grab the URL and paste it back to the slack page (as an event subscription).
