99% of the time stuff like this just handles itself even if you give equal credit on paper: when people ask questions about how it works, who's the one who will have detailed and insightful answers?

And remember the spotlight is always grows big enough to fit the cast: no one's going to view your work in a less impressive light because there's two other names there, and any reasonable person is going to make their best effort to commend/communicate with all three of you if all three of your names show up.

I've been in a similar position but I had the opposite problem: teammates trying to attribute a win to me, and me having to very insistent it was a team effort. I think it's just easy to underestimate how many pieces need to fall in place while you're building on a short timeline and under high pressure. From ideation to implementation, just the presence of teammates can have a strong effect (for all you know, part of your subconscious drive was just to show the other two teammates it could be done!)
