QR code is just text encoded into a graphic. Most modern phones support it and it just makes it so you don’t have to remember or type in a lengthy string of text, like a URL.

Your phone should show you the text without automatically opening the url (if present). I would not open it if it was a domain I did not know and trust or if the domain was encoded (like tiny.url). Which is why I made sure it was a direct Rumble link. No funny stuff.

Hope that helps.
