this example is excellent for use-Cases where the User-ID is known, or the App ID is known. Maybe i am too dumb using bicep but i have trouble with assigning;
multiple Groups, identified by Names and multiple Users, identified by Names to a group as members...

`
//names, or Guids separated by ,
param owner string
var ownerarray = split(owner, ',')
//names, or Guids separated by ,
param member string
var memberarray = split(member, ',')
var groups= [
{
name:'G1'
description:'Desc1'
}
{
name:'G2'
description:'Desc2'
}
]

module Gruppenbesitzer '../modules/user.bicep' = [for own in ownerarray: {
name:'owners-${own}'
params:{
userPrincipalName:own
}
}]

module Gruppenmitglieder '../modules/user.bicep' = [for mem in memberarray: {
name:'members-${mem}'
params:{
userPrincipalName:mem
}
}]
module groups '../modules/group.bicep' =[for (group,i ) in groups: {
name:'somegroup-${i}'
params:{
displayName: group.name
mailEnabled: false
mailNickname: group.name
securityEnabled: true
uniqueName: gruppe.name
owners:[for j in range(0, length(ownerarray)): Gruppenbesitzer[j].outputs.userid] //-> how do i add Groups here, as a whole?
members:[for k in range(0, length(memberarray)): Gruppenmitglieder[k].outputs.userid] //-> how do i add Groups here, as a whole?
