Getting GET or POST parameters via lambda functional

Recently amazon has released Function Url in Lambda.

I just want to know if we can access Query parameters using it , without using the gateway API.

For example https://functionalurl.aws?id=123

I need to get 123

exports.handler = async (event, context, callback) => {
   console.log(event);
   callback(null, {
        statusCode: 200,
        body: context,
        headers: {
          "Access-Control-Allow-Origin": "*",
        },
      });
};

Event is always null when I access the function url.
