How to add the text ON and OFF to toggle button

Question

I wanted to add text to my existing toggle code in my project. So I wanted it to be like this: when toggled ON, it should display the text "ON," and when toggled OFF, it should display the text "OFF." I can't change it to another toggle because it's already in use by a backend. I only wanted to enter the "ON" and "OFF" text. Thank you very much.

This is my code:

 .switch input {
  display: none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: #2ab934;
}

input:focus+.slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked+.slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}


/* Rounded sliders */

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;

<label class="switch"><input type="checkbox" id="togBtn"><div class="slider round"></span></div></label>
