Question about Endgame Encore for first time watch

We are bringing someone to Endgame Encore that has been watching the MCU for the first time up to this movie, and has never seen it before and anything after. We’re trying to make sure she isn’t spoiled for future projects between Endgame and Doomsday in the process of watching this. My friend and I are caught up on MCU, but are avoiding spoilers about what the post credits entail.

Can someone please advise, should we avoid letting her see the post credit scenes with us or do they not spoil projects after endgame?
