Whilst Weekly10 can be added from the Teams app store individually, it is also possible to set Weekly10 as a default app for all (or some) of your employees. In doing this the Weekly10 app will be pinned to the Microsoft Teams toolbar.
To do this you will require Microsoft Teams administrator access and you should navigate to the https://admin.teams.microsoft.com/ screen.
From here select Teams App > Setup Policies from the left bar.
Here you will see the policies set up for your company. Typically you will select the Global (Org-wide default) policy. However, you can set up more granular policies as explained in the MS Teams documentation (https://docs.microsoft.com/en-US/microsoftteams/teams-app-setup-policies?WT.mc_id=TeamsAdminCenterCSH).
Once you have selected the relevant policy you can select any apps you wish to pin to everyones toolbar.
Select Add Apps and search for Weekly10 in the search bar. Select Weekly10 and click Add.
The Weekly10 app will now appear in the list and you can move the order of the app up (select the app then 'Move up'). We recommend Weekly10 should appear in the first 6 apps so that it is visible on the left toolbar of Microsoft Teams. Click Save to complete the set-up.
Once you have made this change Microsoft advise that it may take up to 24 hours to reflect within your employee's Teams toolbar.
