How to download Chrome on laptop?

I have a video conference with my class tomorrow. But for these you need Chrome as a search engine because it somehow doesn't work with other search engines, my teacher said. So I should download Chrome now. There's no such thing in the Microsoft store, just a guide that also costs 3 euro…

Isn't it working on any website?

Chrome should be free, you usually download it from the internet, not from an app store.

I got it again the day before yesterday. I just entered the internet: Chrome download and then I think there's a link at Chip. Then it was installed
