In the below code the returned function is loosing this context. Can someone help me out how to fix this?

Below code looses context of this when I am debouncing a object method. I want to handle this scenario where the returned function can access the name.

// function should return debounced function with this context
    function debounce(cb, delay = 100) {
      let timer;
      return function (...args) {
        clearTimeout(timer);
        timer = setTimeout(cb.bind(this, ...args), delay);
      };
    }
    
    let x = {
      name: "Priyadarshi",
      sayHi: function () {
        console.log("Hi " + this.name);
      }
    };

    // Here returned function looses the this context
    const y = debounce(x.sayHi);
    document.addEventListener("mousemove", () => {
      y();
    });
