Angular newbie here..could someone direct me to the right way how could I replace the existing Material icons with custom ones properly, more precisely with the SVG graphics? Something like this:
So this:
<mat-icon class=mat-icon-rtl-mirror>
{{nestedTreeControl.isExpanded(node) ? 'expand_more' : 'chevron_right'}}
</mat-icon>
With this:
<mat-icon class=mat-icon-rtl-mirror>
{{nestedTreeControl.isExpanded(node) ? 'INSERT_SVG_1_HERE' : 'INSERT_SVG_2_HERE'}}
</mat-icon>
