Function activate_target 

pub async fn activate_target(
    host: &str,
    port: u16,
    target_id: &str,
) -> Result<(), ChromeError>

Activate a target via Chrome’s /json/activate/{id} endpoint.

This uses the same HTTP server as /json/list, avoiding the cross-protocol synchronization gap that occurs when using CDP Target.activateTarget followed by an HTTP /json/list query.

Errors

Returns ChromeError::HttpError on connection failure.
