Connecting your Twitter / X account to your Gleam contestant account allows you to complete Twitter / X-related actions with one click.
All you have to do is click on Connect Your Twitter / X Account from the Gleam widget:
Usually your X login to Gleam has expired or broken. Remove Gleam from Connected apps on X, then log in with X again from the giveaway.
Click Edit on any Gleam widget, then click the × next to the social account you want to unlink.
Reconnect the account. Click Edit next to your name in the widget, unlink the old social account, then log in with it again when the action asks.
