although, I am not an expert on this and I think I am asking a ridiculous query but still I wanted to know, whether I can do automation on a website using RPA or not?

Like, for example, I am logging into suppose, facebook.com, the process of typing the URL and opening up the website on a browser typing into the username and pass (details what needed to be typed automatically provided by the user) into the specific fields and then getting into the homepage.

so, basically I wanna know whether it can be made possible or not, like I am implementing a webpage and it would contain a button and when the user clicks on that button, it would trigger the above mentioned action automatically!

I think using Javascript but if there's a better solution then it would be helpful!
