How to Update Component Attributes without using addAttributes and setAttributes

[RakulAgn]

  private handlePriceVisibility(comp: Component, isChecked: boolean) {
    const newAttr = "hide-summary-product-price";
    let classArray = ((comp.getAttributes()["css-class"] as string) || "")
      .split(" ")
      .filter(Boolean);

    if (isChecked) {
      if (!classArray.includes(newAttr)) {
        classArray.push(newAttr);
      }
    } else {
      classArray = classArray.filter((cls) => cls !== newAttr);
    }

    const updatedClasses = classArray.join(" ");

    if (updatedClasses) {
      console.log(updatedClasses);

      comp.addAttributes({ "css-class": updatedClasses });

      console.log(comp);
    }
  }

This function will add a css-class but the issue is on the first render its not adding it so is there any possible way to update the attributes

You can customize the init method of your component, so you can call it from there
