How can I provide an MS-Teams app to provide link-unfurling and nothing more?

I have an MS Teams app that just does link unfurling. I do not want to provide any actions. I use to be able to do this by just leaving the "commands" section in the manifest empty but now if I do that you get the oh so helpful message "Something went wrong".

So now the only way to get Teams to load my app is if I add a dummy command.

Is there some way to do this without providing commands or some way to provide a command that the user will never see?

This is an actual manifest that fails:

{
  "$schema": "https://developer.microsoft.com/en-us/json-schemas/teams/v1.5/MicrosoftTeams.schema.json",
  "manifestVersion": "1.5",
  "version": "1.1",
  "id": "fe8ad7e8-7679-40d7-9435-0ef4488d74ce",
  "packageName": "com.foobar.teams.1",
  "developer": {
    "name": "foobar",
    "websiteUrl": "https://www.foobar.com",
    "privacyUrl": "https://foobar.com/en/privacy-policy/",
    "termsOfUseUrl": "https://foobar.com/en/terms-and-conditions/"
  },
  "name": {
    "short": "foobar test",
    "full": "foobar test"
  },
  "description": {
    "short": "foobar test",
    "full": "foobar test."
  },
  "icons": {
    "outline": "foobar-outline.png", 
    "color": "foobar-color.png"
  },
  "accentColor": "#FFFFFF",
  "composeExtensions": [
  {
  "botId": "fe8ad7e8-7679-40d7-9435-0ef4488d74ce",
  "canUpdateConfiguration": false,
  "commands": [

      ],
      "messageHandlers": [
      {
        "type": "link",
        "value": {
          "domains": [
          "*.foobar.net"
          ]
        }
      }
    ]
    }
  ],
  "permissions": [
  ],
  "devicePermissions": [
  ],
  "validDomains": [
   "*.foobar.net" 
  ]
}

This is a manifest that works: The only difference is that it contains commands.
