No Settings in Talk for Matterbridge

Hi everyone,
i want to use matterbridge for my Nextcloud Installation. I am unsing nextcloud V. 22.1.0 (Stable) on a Raspberry Pi 4. Talk App V.12.0.1 - Talk Matterbridge V. 1.22.4

When i open an new chat in Talk, i want to go in the menue settings to add an irc channel but there is no setting menue?!? Only ‘Details’ and ‘participant’ are displayed and can be opened.

Is there a nother setting that i must add? or is that a bug?

greetings
