Function admin_text 

pub(crate) fn admin_text(address: &str) -> String

What an organisation’s administrator does, once, for Sioul to read a work or school mailbox, with the link that approves the application in use for the organisation: yours kept on this device, else Sioul’s, and the directory kept from an earlier sign-in, else the address’s domain. Reads the keyring: off the window’s thread (discovery’s). Empty when there is no application to approve yet.
