How to mount system under super partion?

Google has recently changed the way to mount system and introduced Dynamic Partitions . Previously in a rooted adb shell, I used to run mount -o rw,remount /system to mount system in read-write mode. They introduced a new super.img that contains system, vendor, odm, product, etc. I have a simple question: How can I mount a system from a rooted adb shell in recovery? After reading the Implementing Dynamic Partitions guide it looks like I have to 1. create system partition dynamically 2. need an entry somewhere where mount point exists 3. mount the system after the above steps. I don't know how I can do the first step. As the information on the mounting location is inside super.img meta-data and I am unable to read it. Anyone can put some more light here?
