Delete current cell from RG

Hi guys
I am trying to delete current cell from RG

When button ‘Remove’ is clicked current cell thing need to be delete from the database, but its needs something more from me

Note: Database is another Bubble APP where I want to delete the data, probably I need to set up another endpoint to make a call?!
Thanks in advance!

You can either use the App Connector, or set up a Workflow API,
