Imported Material icons looks to big on TabBar

[Sinan-Karakaya]

When importing Material Icons following the documentation, and using them for a tab bar like so, I get the following results:

NavigationStack {
                
}
.tabItem { Label("New", systemImage: "plus.app.fill") }
.tag(Tab.new)

The image on the right appear clearly bigger. I used a tool to make the Material svg conform to what XCode wants for a symbol image set. (This one).

I am not sure what is causing this, I already tried lowering the svg size from 24 to 20, but this didn't change anything.
