Restoration of deleted team

thank you for helping me a lot!!

I do not know why but actually it has been restored, probably by the admin of my organization.

I appreciate you.

... Please note all TEAMs have an O365 Group when created ... https://learn.microsoft.com/en-us/microsoft-365/admin/create-groups/restore-deleted-group?view=o365-worldwide&redirectSourcePath=%252farticle%252fb7c66b59-657a-4e1a-8aa0-8163b1f4eb54&tabs=outlook

if it's an MS TEAMs you won't find it in the SharePoint Online admin center, however I found another article hope it helps ... Restore/Recover Deleted Team | Microsoft Community Hub

thank you for replying.

i meant that it was a team visible on MS teams and sharepoint but not on outlook mailing groups.

unfortunately since it was not archived, the link you sent me did not help it, but i would like to try Sharepoint admin center one. if you have further information how you do that, please let me know.

I'm not understanding the question. If you are talking about restoring a SharePoint Team site, you can restore via SharePoint Admin Center. I guess my confusion is you say "It was not a Microsoft 365 team, only Microsoft teams' team"
