Summary

In the Specs branch documentation Enhanced plan branch configuration It's not mentioned clearly that changes need to be pushed to the specific branch

Also, it says that you can change the repository configuration but not explaining how

When using Specs branches you can’t link any repositories additional to those on master branch. You can change the configuration of that repository but you can’t add or remove it.

Suggested solution

It will be better if we updated the document to explain how to change repository configuration in case of Specs branch being used
