I haven’t tested this but you may be able to potentially do this using the wixLocation API
In the docs it states that it works with
-
mailto:@<someplace.com>?subject=: An email.
-
tel:: A phone number.
Might also work with SMS
import wixLocation from 'wix-location';
$w("#button").onClick(() => {
wixLocation.to("sms://+1800605xxxx? &body=I%27m%20interested%20in%20your%20product.%20Please%20contact%20me.");
});
