Nice job! This is working as expected.

Tested it both with and without the extension installed.

It does have the reverse effect than the original issue where if you are a user without permissions, the banner will take a split second before it shows up - but I think this is the lesser of two evils and the 'Create agreement' button is still disabled so it is not as if the user could try to create the agreement.

Nice and simple, the banner shows up when necessary and not immediately, nice one 💯
