How can i play minecraft world created on ps4 on android device?

My child has created a world on PS4 that he would like to play on the Minecraft app on the go.

He is signed into PS4 on both Minecraft phone with Microsoft account (Xbox). However, you can't see the worlds from each other in both portals.

I ask for help

Doesn't work at all, because it is not the same version. You would have to replicate the whole world.
