Missing auth_token in cookies

[iCankat]

I have successfully implemented Twitter login using this project, and I can retrieve the 'ct0' and 'cookies' as expected. However, the 'auth_token' is missing from the 'cookies'.

Since Twitter requires the 'auth_token' for further operations, I am unable to proceed. Additionally, there doesn’t seem to be any alternative way to retrieve the 'auth_token'.

Could you please guide me on how to address this issue? Is there an alternative method to obtain the 'auth_token' or a workaround?
