According to docs this should be the way to convert b256 to byte array.

```auto
let recipient_bits:b256 = recipient.bits();
let mut recipient_bytes = recipient_bits.to_le_bytes();

```

Errors with:

```auto
No method named "to_le_bytes" found for type "b256"

```

Any idea why?

Found the culprit. For anyone looking, I was missing the import for array conversions:

```auto
use std::array_conversions::{b256::*,};

```
