The "Shopify integration with chat button" plugin allows you to add a chat button to all pages of your Shopify store. This plugin utilizes a custom app from your Shopify account.
If you want to add the chat button only to specific pages, or you want to add a different type of contact widget than a chat button (e.g. contact button), you'll need to use Shopify's theme customization options instead of this plugin, and integrate your widget manually.
