How do I extract data from an API, using a post request, with the HTTP Client snap?

Hi,

The API owner demands I use a post request first, then get authorized by getting a user token and a cookie token, and only then I can do a get request to retrieve the data. I was able to configure the first part properly, in the screenshot below:

This retrieves a header with a token for the user, and the cookie. My question is - what do I do next? how do I configure the next HTTP Client snap in order to retrieve the data with the get request, and what do I choose as an account? should I use the cookies as a token for the account?

Thanks
