I would like to use the membership.fee token in a mail. However, it isn't displayed in the list of tokens the mailer view offers and it's not working when I use it manually. I saw a suggestion to use a membership context, but I'm not sure what that means exactly. I've tried "Find members", saving the list of contacts to a dynamic group and selecting them as recipients, but this won't work either.
I'm running civicrm 5.18.0
