currently I am using MemberGroupService.GetById(Convert.ToInt32(memberGroupStr)) which now says it is obsolete and I should use the guid, however membergroupstr is the value of a MemberGroupPicker on the page whose value is returned as an int, so how to I find out what it's guid should be?

Does this help? https://discord.com/channels/869656431308189746/882984798719729704/1248558690336772096

I was trying that but it requires an UmbracoObjectType, what would that be for a MemberGroup?
