Can not fetch im history with the below bot scopes

I have created an app which is requesting the above bot token scopes
incoming-webhook,commands,channels:history,channels:read,commands,groups:history,groups:read,im:history,im:read,pins:read,reactions:read,team:read,users:read
but when I am trying to fetch the conversations it is returning me only the channels not im conversations...
Must I request any user token scopes ??
