Hello Frida,
I don't see any picture in your post.
However, this link may help you to solve your problem : https://learn.microsoft.com/en-us/microsoft-365/solutions/microsoft-365-groups-expiration-policy?view=o365-worldwide
"Groups that are actively in use are renewed automatically around 35 days before the group expires. In this case, the owner doesn't get any renewal notifications. Any of the following actions will automatically renew a group:
- SharePoint - View, edit, download, move, share, or upload files. (Viewing a SharePoint page doesn't count as an action for automatic renewal.)
- Outlook - Join or edit group, read or write group message from the group, and like a message (Outlook on the web).
- Teams - Visit a teams channel.
- Viva Engage - View a post within a Viva Engage community or an interactive email in Outlook.
- Forms - View, create, or edit forms, or submit a response to a form."
Hope this helps
