manage Exchange Online Mail Contacts with Graph API

Has anyone a solution to manage Exchange Online Mail Contacts over Graph API? This would be the preferred way. On Microsoft Learn I've found this https://learn.microsoft.com/en-us/graph/api/resources/orgcontact?view=graph-rest-beta but it's still in beta and can't be used to create Contacts rn.

Otherwise, I would try to achieve this with the https://learn.microsoft.com/en-us/powershell/module/exchange/new-mailcontact?view=exchange-ps and Azure Automation. I've never got in touch with Azure Automation but what I've seen, it should be possible, I think.
