Hi,
You could add a button and assign it an increment value. Have that value tied to a user-specific column and then filter the Tab’s visibility based on the value of the Increment column (i.e. if Increment = 1, show tab).
In the tab itself, you should be able to add a similar button, but assign it a negative increment value so that the tab disappears once it’s pressed (as the user-specific column would go back to a value of 0).
