I am trying to add a button or widget to my entire site, or ideally just product pages. I would like the button to have custom text along the lines of 'ask a question' that brings up a pop up contact form when clicked. As a very new shop, I'm just looking for a free way (for now, plan can be tiered) that allows me to do this. I added an app called something like NDA Apps which did this but there was a bug on it, and customers couldn't close the widget once opened.
Does anyone know of an app that can offer this?
You can try an app called WhatsApp Chat & Notifications. It's totally free to fit your requirements.
Hope this helps!
