Wix - how to remotely login to external sites

I have a Wix website and a customer portal on another website.

The consumer will log on to my website and go directly to the customer portal without seeing the second login screen. But through the backend the consumer will log in to my website, the information that is placed in the "login and password" will be copied to the second login screen in invisible mode and then it will return to the customer portal in visible mode

I would like to know how I could make this communication invisible. I started seeing libraries like Fetch and Express. I was only able to use it to collect data from other websites, but I was not able to post data from my website to the customer portal.

Then you need to use that token to log the user apply session token
