HandleScope in async op

Is there a way to get v8::HandleScope inside async op if I add it as

scope: &mut v8::HandleScope<'a>,

scope: &mut v8::HandleScope<'a>,

195 | #[op]
    | ^^^^^ the trait `Deserialize<'_>` is not implemented for `&mut HandleScope<'_>`

195 | #[op]
    | ^^^^^ the trait `Deserialize<'_>` is not implemented for `&mut HandleScope<'_>`
