Dynamic group membership

Given that you can indeed filter on createdDateTime in a Graph call, you should have no issues doing so using the Logic App/Function approach you've suggested.

I'm not Logic-anything aficionado meaning I can't guide you through doing that, but here's a basic demonstration of a Graph call in action using Microsoft's Microsoft.Graph.Authentication PowerShell module.

Note that Graph is particularly fussy on the format of [datetime] values. It needs to be in ISO 8601 format while also adding a trailing "Z", as you can see from the example. If it's not in this format you'll get a HTTP 401 response from Graph.

No doubt you're also aware of this but you need to work with UTC time, too.

(Invoke-MgGraphRequest -Method GET -Uri 'https://graph.microsoft.com/beta/users?$filter=createdDateTime ge 2022-08-30T00:00:00Z').value | ForEach-Object { [PSCustomObject]$_ } | ft -AutoSize id, userType, userPrincipalName;
