Best way to build a dynamic data driven navigation, that can be restricted based on security roles

Patrick Rote​ ​ I use the following logic in App.OnStart for "role-based security". If the user is a member of the group, the variable is true, otherwise false.

//Call Microsoft Graph to get all groups the current user is a member of.
Set(
    varMemberOfGroup,
    Office365Users.HttpRequest(
        "https://graph.microsoft.com/v1.0/me/transitiveMemberOf/microsoft.graph.group?$select=id",
        "GET",
        ""
    )
);
// 2) Build a lightweight collection of group IDs.
ClearCollect(
    colGroupIds,
    ForAll(
        varMemberOfGroup.value,
        {id: Text(ThisRecord.id)}
    )
);
// 3) check if the Admin group GUID is present in colGroupIds.
Set(
    varAdmin,
    CountIf(
        colGroupIds,
        id = "xxxxxx-xxxxxxx-xxxx-xxxxxxx"// <-(GUID)
    ) > 0
);
// 4) Same approach as above but for the "Member" group GUID.
Set(
    varMember,
    CountIf(
        colGroupIds,
        id = "xxxxxx-xxxxxxx-xxxx-xxxxxxx"// <-(GUID)
    ) > 0
);

Using /transitiveMemberOf ensures nested group memberships are included.
