How do I add icons to collection list and grid in the Dawn theme?

[john_smith786]

I need assistance in adding icons to the collection list and collection grid on my collection page. When a user clicks on the collection list, it should display the product list, and if they click on the collection grid, it should show the product grid. I am implementing this in the Dawn theme, and I have illustrated it in the image below. Could someone please provide guidance on this?

Note: I have also included the image below for reference.
