How to regain access to emails after cancelling Google Workspace connected to my domain

Hello everyone,

My domain name is : vmacke.com

And I use the offer : OVH Hosting

I have the following problem : I used Google Workspace with my domain vmacke.com and now, after canceling Google Workspace I can't figure out how to regain access to my mails. They don't show up in OVH's webmail, I always used to check them via the Gmail client.
Thanks for any help!
