Web conference auto login script in Microsoft Edge

I'm no master in web development, FYI. This is a web conference website I use daily, and I have to attend after waking up instantly. So I planned a way so if I turn on my Laptop, I attend automatically. Edge is an startup app, and this is the startup page of it. But to complete the goal, the script which logs me in must run with an specific value of username and password when the page opens. Anyway to do that?
