Finding old copyright dispute of video?

I uploaded a video that had a copyright claim, so I ended up uploading another 17-sec video thinking I might avoid the claim, yet I got it again but this time I sent an appeal and my dispute was accepted.
Now, I want to send an appeal to the older video as it had the most interaction ever on my page
So is there somewhere I can access older disputes to send an appeal to my initial video? (now that I know I have the green light)
Or, is there a guaranteed way to access past notifications? (as that notification was way gone)
Or, is there a way to contact the group with the copyright claim directly (although there is no guarantee?)
