New powder snow beach biome?

I was testing the new beta and in the spawn I found snow and powder snow, I thought it was one of the mountains with powder snow but it was only a powder snow beach, I do not know the exact name of the biome, we still do not have that function Here in Minecraft Bedrock but I think it would be a bug and if it is this cool
