How do you determine the members of a project?

When I build, I get this error:

“Because you are not a member of this project this build will not access Unity services.”

I believe this is happening to me because I have multiple accounts. How do I determine which account is associated with the project at hand?

I have a similar problem.
It does not apear to influence my build but would like some help anyway.
Some other posts led me here:

sBut I may not share my project with anyone, so…
Please help, anyone !!!

pretty old topic but it may help someone:
by this method, I didn’t determine the member for the project but hides that message
for me, in the unity 2019.3, the solution was logging out of my unity account in unity editor>Account button (top right)>Sign Out
