I already set the $ point conversion. But it doesn’t show up anywhere and the share button is also not visible.

Per Currency Conversion setting would not be visible to any product page. But if you want to notify users that if they place an order they would be rewarded with some points, you can do this using the “Enter Ways to Gain Points” feature in the General tab of the plugin. Whatever text you’ll put in this text area, it will be displayed on the user’s “My Account” Page.

After enabling the setting “Enable Social Links” and select the social buttons. The social sharing button will appear on the product page, post, etc.
