How to define a heavy object in Matter JS - matter.js

Question

To explain better what I need, think about a tank and a can of soda.
No matter what the speed of that can of soda would be, the tank wouldn't move if it's hit.
But the tank should be able to move when force is applied to it.
Already opened an issue here with more details:
https://github.com/liabru/matter-js/issues/841
And I also made an example here for what I need.
var Engine = Matter.Engine,
Render = Matter.Render,
World = Matter.World,
Bodies = Matter.Bodies,
Body = Matter.Body;
var engine = Engine.create();
engine.positionIterations = 10;
engine.velocityIterations = 8;
var render = Render.create({
element: document.body,
engine: engine,
options: {
width: 800,
height: 400,
wireframes: false
}
});
engine.world.gravity.y = 0;
var topWall = Bodies.rectangle(400, 50, 720, 20, { isStatic: true });
var leftWall = Bodies.rectangle(50, 210, 20, 300, { isStatic: true });
var rightWall = Bodies.rectangle(750, 210, 20, 300, { isStatic: true });
var bottomWall = Bodies.rectangle(400, 350, 720, 20, { isStatic: true });
var ball = Bodies.circle(100, 200, 5, {
friction: 0.05,
frictionAir: 0.05,
density: 0.001,
restitution: 0.2
});
var bigBox = Matter.Bodies.rectangle(500, 200, 120, 120, {
inertia: Infinity,
frictionAir: 1,
friction: 1,
density: 0.1
});
World.add(engine.world, [topWall, leftWall, rightWall, bottomWall, ball, bigBox]);
Engine.run(engine);
Render.run(render);
// CMD + SHIFT + 7 to reload
$('.shoot').on('click', function () {
var speed = 0.02;
var angle = 0;
let vector = Matter.Vector.create(Math.cos(angle) * speed, Math.sin(angle) * speed);
Body.applyForce(ball, ball.position, vector);
});
