I still see a few references to MyPortal in:

• messages.test.ts;
• testFaker.ts;
• MYPORTAL_README.md;

Should we clear them up as well? What do you think?

@LazyAfternoons I think it's a great suggestion, thanks, commit here 2d4bff4e8. I only have a doubt about testFaker.ts, because the PublicSession interface defines (and shares with the backend) myPortalToken as the required property, and therefore should be handled as a blocking dependency. I suggest to resume this point when the same code removal will be done on the io-backend repo.

myPortalToken

Makes sense, let's address this later when the type is changed accordingly.
