New twitch name and nightbot commands are gone

Good morning. I was hoping you could help me with restoring my NightBot commands? I haven't streamed for several years but I'm getting back into it. My old Twitch username was NinjaCowboy, then I switched to Muttyverse which I shouldn't have but it is what it is. Now, my new Twitch name is FishingCaptain. NightBot shows FishingCaptain as a new member since 2026. My old NinjaCowboy had sooooo many amazing commands that took forever to create. Is there anyway we can integrate my old NightBot commands to my new channel name? thank you for your time
