Online Store → Themes → Edit code → theme.liquid. Works on every plan.
Duplicate your theme first (Actions → Duplicate) so you have a rollback point. Takes 10 seconds.
Open yoursite.com in a new tab and hard-refresh (Cmd+Shift+R on Mac, Ctrl+Shift+R on Windows). A dark chat bubble should appear in the bottom-right corner within two seconds.
Not showing up? Make sure you saved theme.liquid and reloaded your storefront (not the admin preview). Text Cal: 308-249-6894.
No subscription required. Cal installs it personally, confirms the bubble is live on your site, and leaves. No upsell, no obligation.
