Get user apps grouped by tabs

We want to get a list of the user apps as in the webapp: /app/UserHome. They are grouped by tabs, the first section is “Quick Access”, then the rest are grouped by user-created tabs.

We noticed that those tab-grouped apps are gathered from the endpoint below which is not listed in the API documentation, at least I couldn’t find it.
/api/v1/users/me/home/tabs?type=all&expand=items%2Citems.resource

So we were looking for more option at the user/app sections but only found options with no grouping info by user tabs.

i.e.

GET /api/v1/apps?filter=user.id+eq+"${userId}"
GET /api/v1/users/${userId}/appLinks

We are trying to use admin read-only token to get this info from different users.

Anyone can help on how to get the apps grouped by tabs for a specific user but using the API ?

Thanks in advance
