initialize an array of std::byte with integer type

I have a

typedef std::array<std::byte, 4> CatType;

And I want to initialize a constant of this type. I can do

const CatType mycat = {std::byte{0x00}, std::byte{0x00}, std::byte{0x00}, std::byte{0x00}};

Which works, but I'd like for readability something like

const CatType mycat = 0x001020ff

Which fails with error

conversion from ‘int’ to non-scalar type ‘const CatType’ {aka ‘const std::array<std::byte, 4>’} requested
