Hi, thanks for your PR!

There are a few issues:

• The icons must be squared (e.g. 32x32 pixels). This one is 30x~22. You can grab one of the already existant icons and use it as guide for positioning.

• I think you're using an older folder shape (we changed the shapes of the folder icons a while ago). You can compare it to another folder icon to spot the differences.

• The material design icon pack has a similar gavel icon. This extension, being a Material Design extension, should use that one instead (IMO): https://pictogrammers.com/library/mdi/icon/gavel/

Thanks!!

I changed the positions a bit, to align the shapes to the grid:
