fix: Session creation request when sending body (#242)

The API was ignoring the data passed as URL parameters but takes it into account when passed in the body.

https://axios-http.com/docs/req_config
- Axios's `params` sets URL parameters
- What the API seems to be expecting here is the body of the request to contain the data
