I am using the Graph API with app permission & with a certificate.

I know how to send emails with the sender which is different from the requestor's email.

I go to admin.exchange.com, select the user and add a mailbox delegation then add the user in "Send as". My question is how to add user with "Send As" option via Graph API only.

I would like use this method microsoft permission: but from graph api

Thanks for your help

No this (and all the other Exchange Admin tasks) aren't currently in the Graph API, the only option for doing this programmatically is to use the Powershell cmdlets https://learn.microsoft.com/en-us/powershell/module/exchange/add-mailboxpermission?view=exchange-ps. The good news is that the v2 Powershell module does now support the client_credentials flow https://techcommunity.microsoft.com/t5/exchange-team-blog/modern-auth-and-unattended-scripts-in-exchange-online-powershell/ba-p/1497387
