Teams staging (sharing side panel app) not working for participants

Question

Hi there,

I'm creating a MS Teams embeded app and this app is working fine in side panel and staging only for meeting organiser but I'm getting same error for participants in both web and desktop app.

Error message- Someone is sharing an app to this meeting. This experience isn't supported in the teams web app.

Here is code of menifest -

{"$schema":"https://developer.microsoft.com/en-us/json-schemas/teams/v1.16/MicrosoftTeams.schema.json","version":"1.0.1","manifestVersion":"1.16","id":"49b4b714-32ad-454e-84e5-6878acb9803b","packageName":"com.package.name","name":{"short":"Ask Dev - 1","full":""},"developer":{"name":"Nitin","mpnId":"","websiteUrl":"https://test-ask.powerappsportals.com","privacyUrl":"https://test-ask.powerappsportals.com/privacy","termsOfUseUrl":"https://test-ask.powerappsportals.com/termsofuse"},"description":{"short":"Ask Dev","full":"Ask Teams extension, web experience for the same:"},"icons":{"outline":"outline.png","color":"color.png"},"accentColor":"#FFFFFF","configurableTabs":[{"configurationUrl":"https://test-ask.powerappsportals.com/config/?teams=true","canUpdateConfiguration":true,"scopes":["team", "groupChat"],"context":["meetingSidePanel","meetingStage","meetingChatTab","meetingDetailsTab"]}],"validDomains":["test-ask.powerappsportals.com"],"webApplicationInfo":{"id":"bb06b670-45d1-435b-82fa-0b1e747c9584","resource":"api://test-ask.powerappsportals.com/bb06b670-45d1-435b-82fa-0b1e747c9584"},"devicePermissions":["openExternal"],"authorization":{"permissions":{"orgWide":[],"resourceSpecific":[{"name":"OnlineMeeting.ReadBasic.Chat","type":"Delegated"},{"name":"MeetingStage.Write.Chat","type":"Delegated"},{"name":"TeamsTab.Create.Group","type":"Application"},{"name":"ChannelMeetingStage.Write.Group","type":"Delegated"},{"name":"LiveShareSession.ReadWrite.Chat","type":"Delegated"},{"name":"LiveShareSession.ReadWrite.Group","type":"Delegated"}]}}}

Please let me know if anything wrong with menifest file.

Thanks in advance.

Answer 1

To allow anonymous users to interact with the tab app, update the supportsAnonymousGuestUsers property to true in your app manifest schema v1.16 or later.

"meetingExtensionDefinition": {
  "supportsAnonymousGuestUsers": true
 }

Thanks,
