I am having an issue granting access to modify Bitbucket pipelines.
I have created an admin group that contains the user I want to grant access to.
I have added this group to the repository as an admin group, N-iX-Admin below.

When they try to modify the bitbucket-pipeline.yaml file they get told they need to be an admin to do so.

I have come to the conclusion I am doing something wrong, but I can't for the life of me work out what.
How can I make this work?
Thanks
Drew
