AppleScript Hash Symbol (#) in URL

I have this Automator AppleScript to translate texts. It works, but only with one word. If I select two words or more to translate, it changes the hash (#) in the URL to %23, like this

https://www.deepl.com/translator%23pt/en/

and I get a 404 Not Found.

on run {input, parameters}
    open location "https://www.deepl.com/translator#pt/en/" & input
end run
