Playlists and Users returned by the API do not include a flag to show if they had been Liked or Followed by the authenticated user.

Title: Playlists and Users returned by the API do not include a flag to show if they had been Liked or Followed by the authenticated user.

Issue found of: March 24th, 2022

Endpoint(s):

• GET /me/activites
• GET /me/followings

Scope(s):

• None (application is not using authentication i.e., implicit flow)

Steps to reproduce:

curl --request GET \
  --url 'curl -X GET "https://api.soundcloud.com/me/activities?access=playable%2Cpreview&limit=20" -H  "accept: application/json; charset=utf-8"'

curl --request GET \
  --url 'curl -X GET "https://api.soundcloud.com/me/followings?limit=20" -H  "accept: application/json; charset=utf-8"'

Expected behaviour:

It would be great if Playlists and Users returned by the API had a flag to show if they had been Liked or Followed by the authenticated user. The same way user_favorite is there for Tracks.

Actual behaviour:

Playlists and Users do not contain an object that indicates whether the authenticated user has Liked or Followed them.

Start by reproducing GET /me/activities and GET /me/followings with an authenticated request, then compare their Playlist and User responses with Track responses containing user_favorite. Done means the returned Playlists and Users clearly indicate whether the authenticated user liked or followed them.
