WHERE IS THE OPTION TO ADD MUSIC TO A VIDEO IN PHOTOS?

Where is the option to add music to a video in photos!?!? Before the iOS update to 15, there was a way to add a song from the iPhone music library to any video in photos. The process consisted of clicking on edit video and then clicking on the circle with three dots button, a drop-down menu would rise up with two buttons: MARKUP AND iMOVIE but within photos.

When you click on iMOVIE it doesn't exactly open the iMovie app but simply brings up a simple editing screen where you can add music from my iPhone music library or even slow down the pace of the video. What was really nice was after letting you use the song you selected from your music library it would allow you to edit specifically when you want to your song to to begin on the video. FOR SOME REASON APPLE HAS REMOVED THAT ABILITY, which is very frustrating because in the iMovie app it is very annoying adding a song to a video. The reason why it is annoying is that compared to the way you czn do it in Photos, iMovie doesn't let you toggle bars of the song to choose where you want it to start specifically you have to trim the audio file to the bar where you want it to start which is a PAIN IN THE NECK.

APPLE, BRING THE FEATURE OF ADDING MUSIC TO A VIDEO IN PHOTOS BACK!!!!
