Non_public metrics retrieval beyond 30 days

[sachingupta049]

Hello,

I am trying to retrieve the non public(private) metrics for the authorized account. I am able to do the authentication using OAuth 1.0a and able to retrieve the data, but I am able to get data only for the tweets which are 30 days old

What are the ways to retrieve the private metrics for the tweets which are older than 30 days?
Appreciate your help.

Thanks
