Enable physics in scene after game starts

Phaser 3
1

Hi, how can i enable arcade physics system in the scene. I know this can be enabled in the game config when the Phaser game is initialize eg:
var config = {
physics: {
default: ‘arcade’,
arcade: {
debug: false,
gravity: { y: 0 }
}
}
};

But how can I enable physics after game is initialize from the scene?

Thanks.

You add the same object (physics.arcade) to the scene config.

Can physics be enabled in the preload() or create function()? What is wrong here?

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    parent: 'phaser-example',
    scene: {
        preload: preload,
        create: create
    }
};

new Phaser.Game(config);

function preload ()
{
    this.load.scenePlugin({
		key: 'ArcadePhysics',
		sceneKey: 'physics',
		url: Phaser.Physics.Arcade.ArcadePhysics
	});
    
    this.load.image('block', 'assets/sprites/block.png');
}

function create ()
{
    window.g = this;
    this.physics.world.gravity.y = 60;
    var player = this.physics.add.sprite(400, 0, 'block');
    this.physics.world.enable(player);
}

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    scene: {
        preload: preload,
        create: create,
        physics: {
            arcade: {
                debug: true,
                gravity: { y: 200 }
            }
        },
    }
};
