What does "this" keyword refer to in a class method?

Question

I have read articles and documents about it and w3schools says:

In a method, this refers to the owner object.

I have this method in a class App class:

_newWorkout(e) {
e.preventDefault();

const validInputs = (...inputs) =>
  inputs.every(inp => Number.isFinite(inp));

const allPositive = (...inputs) => inputs.every(inp => inp > 0);

// Get data from form
const type = inputType.value;
const distance = +inputDistance.value;
const duration = +inputDuration.value;
const { lat, lng } = this.#mapEvent.latlng;
let workout;

// If workout running, create running object
if (type === 'running') {
  const cadence = +inputCadence.value;
  if (
    !validInputs(distance, duration, cadence) ||
    !allPositive(distance, duration, cadence)
  )
    return alert('Inputs should be a positive number!');

  workout = new Running([lat, lng], distance, duration, cadence);
}
// if workout cycling, create cycling
if (type === 'cycling') {
  const elevation = +inputElevation.value;
  if (
    !validInputs(distance, duration, elevation) ||
    !allPositive(distance, duration)
  )
    return alert('Inputs should be a positive number!');

  workout = new Cycling([lat, lng], distance, duration, elevation);
}
// Add new object to the workout array
this.#workouts.push(workout);
// Render workout
this._renderWorkout(workout);
// Render workout on map as marker
this._renderWorkoutMarker(workout);
// Hide and clear form
this._hideForm();
// Set local storage to all workouts
this._setLocalStorage();

What i'm focusing on is the this.x part on the bottom. What does "this" keyword refer to in that code? When I console log "this" it gives me:

App#map: i#mapEvent: Object#workouts: Array(4)__proto__: Object

So it's the "app" class. Yet when i replace "this" keyword with "App" it doesn't work. And when i console log "App" it gives me a similar but different result. Which is this:

  class App {
  #map;
  #mapEvent;
  #workouts = [];

  constructor() {
    this._getPosition();
    this._getLocalStorage();
    form.addEventListener('submit', this._newWorkout.bind(this));
    inputType.a…

So, to repeat my question, what does "this" keyword actually refer to in a method? What am i missing?
