How to convert user mailbox to shared mailbox through graph api?

Question

Hello,

I try to create Lifecycle workflow for offboarding user on azure and my aim to remove all groups from leaver user and I want to convert user mailbox to shared mailbox using logic app in same lifecycle workflow.

I googled how to convert user mailbox through graph api but I could not find correct explanation. Is there any way to convert mailbox to shared mailbox using Microsoft graph?

I found one way which is using PowerShell on Automation account. But Automation account is another resource that's why I don't want to user another resource.

Thank you in advance.

That still requires Exchange Powershell and set-mailbox.
