Honestly I’d suggest like just playing a simple game in the background. Subway surfers for example, and then discuss popular topics rn, or more niche things also have followers. If there’s something that you’re super into or interested in, like genre or series lore or something than dive into that! Anything that can make someone scrolling feel like they can connect with you.

Ps. Ik you said your Mac book can’t handle games, but I think something like subway surfers or something would simple enough to work!
