library(shiny)
library(shinymaterial)

# Wrap shinymaterial apps in material_page
ui <- material_page(
  title = "Basic Page + Side-Nav with Tabs",
  nav_bar_fixed = TRUE,
  # Place side-nav in the beginning of the UI
  material_side_nav(
    fixed = TRUE,
    # Place side-nav tabs within side-nav

        "Example Side-Nav Tab 2" = "example_side_nav_tab_2"
      ),
      icons = c("cast", "insert_chart")

Have you tried opening the Shiny app in your web browser? When I run the app locally in the RStudio viewer the icons will not load, however, when I open the app in the browser they load for me using the code you shared
