Issue Adding App to Shared Channel

[infinire]

I've developed a bot application for Microsoft Teams and have encountered an issue accessing it within a team's shared channel. Following the guidelines provided in [this document](https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/shared-channels#en...), I've added the 'supportedChannelTypes' field to the manifest and published it within my organization.

Despite clearing the cache from the '%appdata%\Microsoft\Teams' folder and restarting the Teams app, the problem persists. Below is a snippet of my application's manifest:

```
"supportedChannelTypes": [
        "sharedChannels",
        "privateChannels"
    ],
    "staticTabs": [{
        "entityId": "issuesTab",
        "name": "Tasks",
        "contentUrl": "${{PROVISIONOUTPUT__AZUREWEBAPPBOTOUTPUT__SITEENDPOINT}}/api/issues?userEmail={loginHint}&type=ado",
        "scopes": [
          "personal"
        ]
}]
```

I would appreciate any assistance or guidance you can provide to resolve this issue promptly.
