A link in a MirageCHAT email — a conversation, Billing, Channels — now opens that screen. If you are signed out, you sign in first, with your password, Google, Apple or Facebook, and land on the page the link names instead of the Inbox. A conversation from another workspace says Conversation #… isn't in the workspace you're signed in to.
On iPhone and Android, the MirageCHAT app opens on the screen the link names.
