When configuring or adding entity mappings in the Bindings page, the user gets "You are not authorized to perform this request." error message.
The user making the changes has insufficient permission on a project level.
Locate the project you want to configure the bindings for.

Next, click Actions > Edit permissions.
Make sure the user who is configuring the mapping has the following permissions:
(a.) Project Permissions:
i.) Administer Projects
ii.) Browse Projects
(b.) Issue Permissions:
i.) Create Issues
ii.) Edit Issues
iii.) View Issues
(c.) For Jira Cloud, ensure that the atlassian-addons-project-access role is granted with all the permissions.
