Having trouble accessing this.request_access() within the DetectRTC.load function using stimulus JS

  _check_permissions() {
    var cards = (this.cardsTargets);
    
    DetectRTC.load(function() {
      this.request_access() //this won't run
    })
  }
  
  request_access() {
    
  }

The only way I can access it is to pass this into the _check_permissions(this) as a param and use that to call request_access() function from the passed param like this:

  _check_permissions(this)

  _check_permissions(context) {
    var cards = (this.cardsTargets);
    
    DetectRTC.load(function() {
      context.request_access() //this works
    })
  }
  
  request_access() {
    
  }

is this the proper way to do this? Is there a more convential way to do this?
