iOS 18 Combining multiple Live Photos to video

I recently updated to iOS 18 and now I can’t figure out how to combine multiple Live Photos into one video. I can still turn one Live Photo into a video by viewing the photo, tapping the 3 dots, and tapping Save as Video. However, I can’t figure out how to combine multiple Live Photos into one video. I used to be able to do it by selecting which Live Photos I wanted to include in my video but now that option is gone. Is there another way to do it that I’m missing? Thanks.
