How to share a bit bucket repository with another user?

I am using Bit bucket and I have a friend that I would like to share my repository with. I am using the free individual account. There seems to be an option of creating a team in bit bucket but it says it will convert my account from individual to team account. I do not want that. How can I give another user access to this repository?

How do I give someone admin access to a project in Bitbucket?

Go to Settings > Permissions for the project. Click in the Add Users or Add Groups fields in the relevant section to search for, and bulk add, users or groups. Choose a permission from the drop-down list, then click Add.

There is an option of share link, if you click on that, a popup will be appeared on that you can give your friends username or his email to share the repository. This popup says something like "Existing users are granted access to this repository immediately. New users will be sent an invitation."

UPDATE: Looks like the interface is slightly changed. You can share a repo via Settings / Access management.
