Excel Office Script, User Input

Question

I am currently using excel web and I was trying to find a way to have an input box to get some user input but I couldn't find in the api or any answer online in that regard.
All the answer i've found were using VBA but since its excel on the web VBA don't work in this situation and the only way i found for scripting was with Excel Office Script.
Would anyone have an idea how I could get some input from the user when the script is ran.

PS: The type of Input i am looking to get from the user is a simple string
