[TOMT] [song] help me find a song I saw in early 2020s

I probably heard the song around 2-3 years ago on YouTube. I saw it in an animatic for some Disney channel cartoon, most likely owl house or Amphibia, but I could have saw it somewhere else. I only remember the line “Forever and ever.” I believe it was at the end of the song. It had a soft, somewhat melancholic melody. I know a girl was singing it. If I’m remembering correctly, the closest comparison to the voice was the person singing the background vocals in Know who you are from moana, but I don’t know if it’s the same person. I don’t remember the melody that well either, or how it went.
