Popup wont go away!!

My friend invited me to their relem, and I used the invite at the top of the screen to play originally. I have since then closed it and started it back up many times and still was able to play. Today I loaded up minecraft, clicked the relem and saw the popup as usual. But it wouldn't go away. Since I have no invites as I'm already in the relem, I don't want to buy a relem or use the subscription as I have to add a credit card. There is no exit button and I can't click off of any of it. I'm going to ask my friend to invite me again, maybe by kicking me and re-inviting me.
