Anything on Android like Samsung Sound Assistant that allows you to change the volumes of each app individually while they play simultaneously?

I'm changing phones after 6 years (from Samsung Galaxy S9+ to OnePlus Nord 4) and OneUI has been very convenient, Good Lock and odd. I find it easier to not mind the differences too much, but I have a habit of listening to music and watching videos/listening to audiobooks together, and it's kinda unbearable. I haven't been able to find any alternatives as of yet. The features I mainly use are: 1) Individual app volume - allows me to control the volumes of each app individually. 2) Multi sound - to allow Spotify or YouTube Music to continue playing in the background no matter what I do. For example, whether I start video recording or play a video. 3) Separate app sound - only use this sometimes when I want to continue playing music on the speaker separately while all the other stuff I do doesn't affect the app playing on the speaker.
