In certain environments, installing the Teams app might not be possible, not even by the team owner.
There are two ways to enable the app anyway, though an approval of a Microsoft Teams administrator will be required.
Option 1: Allow team owners to install apps by themselves

This is the option Microsoft recommends. This option is active by default.
AzureAD portal
Permit app installation by going to: https://portal.azure.com/#blade/Microsoft_AAD_IAM/ConsentPoliciesMenuBlade/UserSettings
And allow team owners to install apps by themselves.
MS Teams admin center
Go to app permission policies: https://admin.teams.microsoft.com/policies/app-permission
Choose the policy that is assigned to your Jira users in Teams (of if you just have the global one, choose this.)
MS Teams admin center
Allow installation of 3rd party apps by the applicable app permission policy (or just allow the installation for our Microsoft Teams - Smart Connect for Jira app.)
Please note: It may take up to 24 hours for the app to be visible for users in Teams.
Option 2: Install the app for certain teams manually

If non of the above works, Microsoft Teams administrators can also add apps on an individual basis.
MS Teams admin center
Go to: https://admin.teams.microsoft.com/policies/manage-apps
Search for our app → add it to the desired team via “Add to team”.
In case the app is not allowed by default, it might also be necessary to allow the app first (see above).
Heads up
In case you see this error below, it usually works and the app should be installed. There currently seems to be a bug on the Microsoft side regarding this.
