When setting up a federation, before sharing resources, one party needs to generate an invite token and the other one needs to accept it. What is maybe clear to devs is not for ordinary users. This is because the step is two fold: invite to federate and share resources Using the term `Invite users` without context can lead to misunderstanding about the purpose. Therefore `Invite users` should be rephrased to `Invite users to federate`.  @JammingBen
