How to give access to only a specific branch on bitbucket?

Question

Remote access

Hello dear.
Tell me the following:
How to give access to only a specific Branch on bitbucket? I see that you can send an invite to the user after giving him read or write permissions, but this is to the repository, as I understand it, but it is necessary that the branch user does not have write access to the main one.
Thank you.
ps. how difficult it is on bitbucket in an organized way ..

Settings -> branch permissions. It's very difficult, yes...
