Can't create deck cards from Desktop Client

[lars-becker]

Is your feature request related to a problem? Please describe.

In the web client it is possible to convert a message to a deck card. This option is missing from the desktop client.

Describe the solution you'd like

A possibility to convert a message to a deck card would be quite handy.

Describe alternatives you've considered

Switching to the Browser is time consuming and no simple workflow.

Additional context

For the existing integration to the web client see nextcloud/deck#2630

• Depends on Load additional installed apps from server #323

Currentlty Desktop Clients works as a client and only supports Talk features like other clients.
It doesn't support features that are added by external JS scripts from server rendering from additional apps.
