make request for cookies inside createSessionFunction

Dear all, I am trying to use createSessionFunction to create a session and set some basic cookies from a response. The problem is how can I make a request to an endpoint to get a cookies inside createSessionFunction ?

My basic code is this and am wondering what is the best way to get cookies without breaking the flow of the crawler.

createSessionFunction: async(sessionPool,options) => { const session1 = await sessionPool.getSession(); const proxyurl = await proxyConfigurationEU.newUrl(session1.id); // Get cookies session1.setCookiesFromResponse(response); return session1 }
