What permissions are necessary for the Tempo apps to work properly?

1. Browser Users and Groups. Please, verify if the Atlassian Add-On Administrator group (atlassian-addons-admin) has the Browse users and groups permission in the JIRA Global Permissions. *This permission is essential for the plugin to work properly.* 

2. Browse Projects permission. Please verify if the "atlassian-addons-project-access" project role has "Browse Projects' permission under project permissions and 'Edit Issues' under issue permissions. You can verify this in "Projects > View All Projects > project name > Project settings > Permissions". If not, grant the role these permissions. 

3. Administer Jira permission. Please, make sure that the group atlassian-addons-admin has the Administer JIRA permission in Global permissions.
