it seems while TEL:// works, I would like to have a SMS:// URL work in my Shopify theme (Sense/Dawn). I purchased a plan for text messaging support (using services like SimpleTexting, etc.) since I’m running this business solo, and answer queries through text messages much more easily.
Is there a way to edit code to “allow” SMS:// url format to be allowed in the theme? I’m comfortable with editing code, and have theme code backups already.
