What to do for Fiance

My fiance is in a casual valorant team and he's been thoroughly enjoying it. It brings up his mental health and, though sometimes the chats are toxic, it sounds like his team's girlfriends and wives are supportive by playing with them or giving them skins. I know nothing about it and would love to support my future hubby, too. One wifey somehow got some special skin from a game Dev? I'm wondering, as I don't play and shooting games are too anxiety-provoking for me, what other special ways can I support him?

He has a twitch and I am starting to watch/keep the stream on my phone as I do other things. I thought of subbing, but our money is pooled and I feel it wouldn't have the same effect. Please help a fellow gamer's future wifey to support him! Thank you.

TLDR: how to support valorant fiance that doesn't include watching his streams on twitch.
