To name a few bigger ones, there was the concert in Osaka, Aim higher concert (with Rofmao), Nijifest 2022 stage, both of their solo concerts, etc.
They a lot of covers and 2 albums with their original songs, you can look at their yt channel.
They're not 100% dedicated to doing their unit idol content because they need to balance out a lot of things (different types of content and also solo vs unit) but they still release plenty. I don't think there's any duo that does as much as they do.
