I have been using my plugin earlier in late 2019 (1 month ago)
today I have loged in and there was message
I have went to group permission added the jira-addons-admin and once again it is showing same message.
You need to add 'atlassian-addons-admin' group to Browse users and groups global permission.
If you are a Jira admin, you should be able to access Global permissions page using the below link. You will have to change the hostname in the URL to your Cloud hostname.
