Is it possible to call predicate from contract side?

Hi there
Is there any chance to call predicate from contract like here?

              asset_id: OFFERED_ASSET,
          };
          
          
// Change output for unspent asked asset
          let output_asked_change = Output::Change {
              to: Address::from(taker_wallet.address()),
              amount: 0,
              asset_id: asked_asset,
          };
          
          
let script_call = ScriptCallHandler::<()>::new(
              vec![],
              UnresolvedBytes::default(),
              taker_wallet.clone(),
              provider.clone(),
              Default::default(),
          )
          .with_inputs(vec![input_predicate, input_from_taker])
          .with_outputs(vec![
              output_to_receiver,
              output_to_taker,

It is not possible to call a predicate from a contract, as predicates aren’t deployed on chain.

+1 to @furnic’s answer. However, the linked file is a Rust test utility function, not a contract. The function creates a transaction to interact with a predicate. That is possible.
