Not sure it should be there or in the Conversation+ menu?

Or maybe via the search field in the left sidebar?

Suggested change

	return { error: t('talk_desktop', 'Opening conversations from other servers is not currently supported'), token: '' }
	return { error: t('talk_desktop', 'Opening conversations from other servers is currently not supported'), token: '' }

I'd prefer something that will also work for joining as a guest in the future. And if possible - more visible.

Or maybe via the search field in the left sidebar?

This sounds nice but seems a bit hidden to the end user. You need to know that you can past a link to the search field. And still handle errors.

Sound good, that would match competitors:

Can we do a component in spreed and use it with @talk/src in desktop?

I am unsure if I understand what component you want to add and where to use, but in general we should never directly use files from talk in desktop or vise versa. It should be a public API, like API to extend one app by another we have in other apps.

For example, we may have the link/component on the web all the time, but have slightly different handling or optional handler registration in the future when the multi account is supported.

Essentialy, public API to spawn a dialog window from this PR would be more than enough
