Adding a Strava icon to Header and Footer

Site URL: https://katie-remond.squarespace.com

Hi everyone

I'm currently building a website and would like to add my clients strava profile link to both the header and footer of her website. Ideally have the strava icon replacing the 'link' icon that is used now when adding a customised link

How would I go about doing this? Does someone have a guide?

Thanks

Ed
