How to allow group editing in Experience Builder

[RachelHall]

I have made an map on Experience Builder, and I was trying to figure out how to allow for someone else to be able to edit the map as well. I am in a group, I am not in charge of the group and I have shared the map and no matter which settings I seem to select it doesn't allow for other people to edit the map. Does anyone know how to fix this?

Items shared to "Shared update groups" can be edited by group members.
