Find the SharePoint rule very exciting. The problem with PowerAutomate is that the flow starts with every change and only then the check takes place. This can cause a lot of unnecessary traffic (api calls).
But at most in combination of SharePoint rules, trigger Outlook (SharedMailbox) and then the normal flow, this is certainly very helpful.
