deep link to teams channel tab using entityId

Hi,

I a have deep link navigation issue - I am simply trying to navigate to a channel tab in Teams.

Here is the tab information, according to Graph API:

{
    "id": "7e8e4ab6-288b-434c-9959-d9c89dc49913",
    "displayName": "Fable",
    "webUrl": "https://teams.microsoft.com/l/entity/[removed for brevity]",
    "configuration": {
	"entityId": "club-54112bf5-f765-4f6a-9c67-27e281921638",
	"contentUrl": "https://[redacted]/club?channel=19:c1e4970eb1a9479aac1c0b4168ce5e9a@thread.tacv2",
	"removeUrl": null,
	"websiteUrl": "https://[redacted]/club",
	"dateAdded": "2024-01-16T23:06:24.163Z"
    }
}

I use the entityId above to navigate to the tab as follows:

function createTeamsAppLink(params) {
  const url = new URL(
    'https://teams.microsoft.com/l/entity/' +
      encodeURIComponent(params.appId) +
      '/' +
      encodeURIComponent(params.pageId),
  );

  if (params.webUrl) {
    url.searchParams.append('webUrl', params.webUrl);
  }
  if (params.channelId || params.subPageId) {
    url.searchParams.append('context', JSON.stringify({ channelId: params.channelId, subEntityId: params.subPageId }));
  }
  return url.toString();
}
const url = createTeamsAppLink({
  pageId:'club-54112bf5-f765-4f6a-9c67-27e281921638', 
  appId: '24d6d825-3472-47c3-a81a-6a88b90322f5',
  channelId: '19:c1e4970eb1a9479aac1c0b4168ce5e9a@thread.tacv2'}
)

microsoftTeams.executeDeepLink(url);

The above code navigates me to the correct channel but it does not open my app tab (it opens the default tab for the channel).

If I replace pageId above with either of the following values, the navigation to my channel tab works perfectly:

pageId: '_djb2_msteams_prefix_223818790' or

pageId: '_djb2_msteams_prefix_7e8e4ab6-288b-434c-9959-d9c89dc49913'

However I don't think I am able to access the internal tab ID without elevated Graph permissions (in my application I am trying to use minimal permissions).  According to the docs, the entityId I used when creating the tab should work for deep links, so I am puzzled why it is not working for me.

Thanks for any help!
