BUG when Adding GPT to Sheets

When you try to add the GPT feature, another security login sheet appears and requests you to login. Once finished, you need to go back manually to your Sheets Tab and GPT is still not activated. The proper behaviour should be that when a user click on Sign in to GPT, once finished with sign in, the sign in tab or pop up windows closes, the Sheets tab becomes the active tab and the user no longer need to login as GPT is active and the user is logged in.
