Default messages are added asking the user to plug in their Trezor device (device.connect) and about the TrezorConnect popups (trezor.connect.generic).

Subclasses should override this method and add their own messages (don't forget to call super()).

(async) run() → {Promise}

Awaits the call of this.method, passing in the output of this.params().

Otherwise it returns the result of passing result.payload to this.parsePayload.
