SkypeBot authentication has been denied

Question

Hello,

I have problem when make a API call to skypebot

For authentication I have followed this instruction (https://learn.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-connector-authentication?view=azure-bot-service-4.0&tabs=multitenant) and success login to get the JWT token.

   {  
       "token_type": "Bearer",  
       "expires_in": 86399,  
       "ext_expires_in": 86399,  
       "access_token": "eyJ0eXA...KC_gw"  
   }  

and then, use access_token to make another request to https://smba.trafficmanager.net/apis/v3/conversations/{conversationId}/members, of course have added Authorization: Bearer eyJ0eXA...KC_gw, but got issue

   {  
       "message": "Authorization has been denied for this request."  
   }  

In my application detail, have a warning message

Starting November 9th, 2020 end users will no longer be able to grant consent to newly registered multitenant apps without verified publishers. Add MPN ID to verify publisher

Please to be advised should I need to do for now to move forward

Thanks.
