Impossible to Open Modal Dialog in Team Chat

As per the card builder UI, I’m trying to use this action to create an action that opens a modal dialog:

          {
            "text": "Open app modal",
            "value": "connect",
            "style": "Default",
            "action": "dialog",
            "dialog": {
              "size": "S",
              "title": {
                "text": "Advanced Options"
              },
              "link": "https://blue-olympia-67.tiiny.site/"
            }
          }

This json is sent by my chatbot app and renders OK in the client BUT when I try to open the dialog on the client, I keep receiving an error that does not include sufficient information to investigate.

I have added the domain to the allow list for the app but still I get the error below…

Something went wrong
Error code: 0x20000

I can’t find any documentation for how this should be setup.

Please help.
