Every time a user visits your website,
they would be prompted to login in order to check live status
Which is bad practice and users probably wouldn’t bother.
So it’s not “compatilble” with webflow, as you need a backend to do this sort of stuff efficently.
Otherwise you are looking at implicit auth
see this example: https://barrycarlyon.github.io/twitch_misc/authentication/implicit_auth/ just swap the /user lookup for a streams lookup instead.
