Invalid access token, does not contain scopes

Hi,

My App Name: Indian Express

I am trying get metrics of live webinar using OAuth credentials. but getting below error.

I am using "/metrics/webinars/{webinarId}/participants" this api.

I have already added "dashboard_webinars:read:admin" this scope in my app.

Unable to find "dashboard:read:admin" this scope in scopes section for my app.

Error: '{"code":4700,"message":"Invalid access token, does not contain scopes: [dashboard:read:admin, dashboard_webinars:read:admin]."}'

I have already added scopes in my app still getting error.

Please find attachment.

Thanks
