When I invite a new member to a Team Workspace… that person can see and execute requests in the Workspace… but the “Save” button is greyed out… is there a way that I can give permission to modify and save requests and collections?
Welcome to the community
Yes, as you are the owner of the collection (“Editor” role) while new member will have a “Viewer” role automatically assigned. To provide the new member with “Editor” role, click on collection > Manage roles. Providing “Everyone in the team” “Editor” access will let them modify/update requests.
