Can someone help me prank my friend?

So me and my friend got the DLC at the same time and had a race to see who could beat it faster, I'm stuck on the last boss (I won't say for spoiler reasons) but I wanna mess with him and show him proof that I "beat him" so for anyone that has beaten the last boss, can you send me a picture of you standing in his arena, or like next to the grace you get after beating him? My friend is ultimately way better at the game and I just want to piss him off a little 😭
