MUI Grid - Hide scroll bar, but while still being able to scroll

Question

I'm trying to do exactly the same as this post but with the implementation on a MUI Grid container/item. The result though is that I don't have a scrollbar and I can't scroll. Is there something wrong with my implementation?

Here is the codebox

Thanks in advance for your time.

Edit, apparently the links are working so I'm altering this post with both the links and the code.

Code:

const ScrollableGrid: React.FC = () => {
  return (
    <Grid
      container
      sx={{ overflow: "hidden", maxHeight: "300px", border: "1px solid green" }}
    >
      <Grid
        item
        xs={12}
        sx={{
          overflowY: "auto",
          height: "100%",
          boxSizing: "content-box",
          border: "1px solid red",
          margin: "10px",

As my comment worked, I'm adding this for other users.

You can hide the scrollbar but keep the functionality like so:

.HideScrollbar {
  -ms-overflow-style: none; /* IE and Edge */
  scrollbar-width: none; /* Firefox */
}
.HideScrollbar::-webkit-scrollbar {
  display: none;
}

You can hide the scrollbar by adding the following to index.css or your root CSS file.

/* Hide scrollbar for Chrome, Safari and Opera */
.example::-webkit-scrollbar {
  display: none;
}

/* Hide scrollbar for IE, Edge and Firefox */
.example {
  -ms-overflow-style: none;  /* IE and Edge */
  scrollbar-width: none;  /* Firefox */
}

And use the CSS classname in your div.

<div className="example">
  <-- Content goes here -->
</div>
