How do I know a gmail account is a member of Google Groups?

Question

I am creating a web app with Google Apps Script. I want to know if an app user is a member of Google Groups.

It is not groups managed by G suite.

Create a Google spreadsheet. Open this and add the group's email in the sharing task.

When I open a file shared by a group in a script and open it, can I verify that it is a member of the group?

I want to qualify only members of the Google Group to be members of the Google Team Drive. — user6338904
How will you access the list of users in a group? If the group is not in G-suite are you the owner of the group? — Jason Allshorn
I am the owner of the group. But it does not matter. I need a way to know the members of a group in the webapp. Here are the scenarios: I create a spreadsheet file on Google Drive. Then invite the group to view this file. I can find the group members by adding code to open the file in the Script Editor. — user6338904

What's available from Google's API is the Members.list.

Retrieves a paginated list of all members in a group.

Give it a try.

Haven't really tried it but the Apps Script version seems to be getUsers().
