Missing request_id type in OauthTokenResponse

[MohammedEsafi]

Description:

Currently, the OauthTokenResponse does not include a field for the request_id type, even though this field is included in the actual response. this absence leads to a type error in a specific use case where I encounter the issue while utilizing that field.

To address this issue, I have to cast the token method response. however, I believe this should be resolved within the library itself. I plan to open a PR to address this issue.
