email blocked with subdomain in workspace

[nettux]

Hey guys! I need to create a subdomain for the workspace, eg teacher.edu.mydomain.com so that teachers can access the Workspace using account@teacher.mydomain.com but I'm having trouble creating the notes on Cloudflare, could someone help me to help?!

Hello my friends!
I hope everyone is okay!
I managed to solve the problem and I want to record it here so that other people can benefit.
At Cloudflare I created the subdomain professor.edu.mydomain.com, created those standard Workspace notes (alt1... etc), created a TXT type for DKIM and for each subdomain there is a DKIM and an SPF (that was the problem - I was using the @ in the SPF, it was enough to create an SPF for the subdomain.mydomain.com) and it worked.
