Polished andesite in Minecraft does not go with commands?

I wanted to build a city recently and use the / fill command (Minecraft PE)

So I entered the coordinates and searched for poilished_andesite which did not exist, the same with normal andesite

only the polished andesit stairs and the normal andesit stairs are displayed, does anyone know why this could be or whether MC PE simply does not allow that?

Should go, I think "/ fill x yz x1 y1 z1 minecraft: stone 6"

polished

its /fill 4637 304 -391 4659 291 -391 stone ["stone_type": "andesite_smooth"]
