Is it possible to access the "Name" value in a SP members group using REST? I'm able to reach LoginName, Id, Email, but not Name. My ultimate goal is to pull out all users from a group with specific text in their "Name" field. Thought I could use REST to filter this but it doesn't look like the "Name" value is exposed in anyway. I have two classes of users appearing differently in "Name" field: John Doe User1 and Jane Doe User2. I'm only trying to pull the User1 Name values that are displayed. Is this possible via REST?
Here is the link I'm currently using: 'mysite/_api/Web/sitegroups(12)/users?$select=LoginName'
