Font-awesome, Line-awesome or Bootstrap-icons in Metronic for Angular
I would like to know how to use font-awesome, line-awesome and bootstrap-icons icons in Metronic for Angular. Because even the demo provided by Keenthemes for Metronic for Angular doesn"t correctly display the icons.
As seen here: https://preview.keenthemes.com/metronic8/angular/demo2/crafted/pages/wizards/horizontal
After the title "Choose Account Type" should appear the icon "fas fa-exclamation-circle" but nothing is rendered.
