Display hidden text in a circle following the mouse cursor

I'm looking for help to display a text "hidden" behind another text when the mouse passes over it, in a circle following the cursor. I found a solution with mix-blend-mode and CSS masks, however, this solution lets both texts appear in the circle according to the chosen colors (see below with black and purple) and I want only the purple text to be displayed in the circle. I thought about using clips, but I can't get out of it. Do any of you have any idea how to do this?

Thank you in advance for your help!

jQuery(document).ready(function($) {

    var timer;
    var mouseX = 0, mouseY = 0;
    var xp = 0, yp =0;
    var circle = $("#circle");

    function mouseStopped(){    
                                 
        circle.removeClass('moving');
    }
   
    $(document).mousemove(function(e){
         
        circle.addClass('moving');
          mouseX = e.pageX - 160;
        mouseY = e.pageY - 160; 
       
        clearTimeout(timer);
        timer=setTimeout(mouseStopped,3000);   
    });
    
    
    var loop = setInterval(function(){
       xp += ((mouseX - xp)/12);
       yp += ((mouseY - yp)/12);
       circle.css({left: xp +'px', top: yp +'px'});  // 
    }, 30);

});
body, html {
    position: relative; 
    overflow : hidden;
    height: 100%; 
    width : 100%;  
    margin: 0;}


.pro {
    color: #000;
}

.perso {
    color: #6230e1;
}

.full-size { 
    height : 100%; 
    width : 100%; 
    position: absolute; 
    top : 0; 
    left : 0;
}

.blend-darken {
    mix-blend-mode : darken;
}

.blend-screen {
    mix-blend-mode : screen;
}

.mask-bg-color {
    background-color: #fff;

.animated-bg {
    background-color: black; 
}
.element-mask {
    background-color: #fff;
}

.circle-follow {
    position :absolute;
    overflow : hidden;
    background-color: #000000;
    width :320px; 
    height: 320px;
    top:calc( 50% - 160px); 
    left:calc( 50% - 160px); 
    -webkit-border-radius: 160px; 
    border-radius: 160px;  
    -webkit-transition: opacity 0.9s cubic-bezier(0.52, 0.01, 0.16, 1);  
    transition: opacity 0.3s cubic-bezier(0.52, 0.01, 0.16, 1);  
    opacity : 0; 
}

.circle-follow.moving {
    opacity : 1;
}

You can do easier like below using clip-path

jQuery(document).ready(function($) {
  var timer;
  function mouseStopped() {
    $(".perso").removeClass('moving');
  }
  $(document).mousemove(function(e) {
    $(".perso").addClass('moving');
    $(".perso").css({
      '--x': e.pageX,
      '--y': e.pageY
    });
    clearTimeout(timer);
    timer = setTimeout(mouseStopped, 3000);
  });
});
body {
  margin: 0;
}

.wrapper {
  position: relative;
  min-height: 100vh;
  color: #000;
}

.pro,
.perso {
  padding: 1em 0;
  margin: 0;
}
.perso {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  color: #6230e1;
  background-color: black;
  clip-path: circle(0px at var(--x, 0) var(--y, 0));
  transition: clip-path 0.3s cubic-bezier(0.52, 0.01, 0.16, 1);
  cursor: pointer;
}

.perso.moving {
  clip-path: circle(160px at var(--x, 0) var(--y, 0));
  transition: clip-path 0.15s;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="wrapper">
