 Pleroma has mechanism that allows frontends to save blobs of json for each user on the backend. This can be used to save frontend-specific settings for a user that the backend does not need to know about.

 The parameter should have a form of `{frontend_name: {...}}`, with `frontend_name` identifying your type of client, e.g. `pleroma_fe`. It will overwrite everything under this property, but will not overwrite other frontend's settings.

  The file list will be written to the file specified previously, *replacing* that file. You _should_ check that the file list doesn't contain anything you don't need in the pack, that is, anything that is not an emoji (the whole pack is downloaded, but only emoji files are extracted).
