OTDS Authentication with Cognito token

Options

I`m having problems authenticating AWS Cognito users, I need to do operations in the repository with their credentials, and I cant find a way to create a IDFSESSION,

I can take their credentials, authenticate then against aws and get an access token, but I can`t find an example to take that token, and pass it to DFCs, DFSs or DCTM Rest,

Checking OTDS webservices I found these endpoints /otdsws/services/Authentication?wsdl, can I use any of these endpoints to translate the AWS token to a DCTM ticket, a otds token on any other way to have access to the repository functionality,

are DFCs capable of taking a token string and instantiate a session?
