Easy way to get the root node

[itsyaasir]

Hey! I am trying to get the full root node of the trie and I have tried couple of ways which doesn't seem to return any results! one of the ways I thought will work was doing something like this

    let root_entry = tx.get::<tables::AccountsTrie>(StoredNibbles::default())?;

the assumption is that empty nibbles returns the root entry but this didn't work for me! can anyone assist me with this ?
