Load Test 500 users

How do I perform load testing on my glide app? I will have approximately 500 users accessing the app at the same time. My calculations are all on the google sheets and quite complex, so I want to know the approximately how much waiting time should a user expect after giving his inputs. Please suggest some ways to perform load testing.
