How to restrict access to specific repositories on BitBucket?

Question

Bitbucket

Given:
1) There is a team on BitBucket with projects attached to it.
2) The team has repositories test1, test2 , test3.
3) There is some remote user that is attached to the team (has a connection via ssh)
4) As a result, the user can access both test1, test2, and test3.
Question:
Is it possible to restrict access rights so that the user has read and write access only to test1? And the other, for example, at the same time had access only to test2? How can this be implemented?
