How to implement aggregate rating schema on Webflow?

Hello all !

Any of you guys have an idea how to implement aggregate rating schema on Webflow that looks like this ? https://whitespark.ca/wp-content/uploads/2018/05/kofc-review-rich-snippet-1024x283.png

Maybe there is somewhere in this forum a step by step process to do so ?

For your information, we are a software and we do not host aggregates on our site, but we use external solution (ex:capterra) that host aggregates for us.
Is this possible in our case ?

Thank you in advance,

Dan.

You will need to look at a third party tool to add ratings. Here is a popular one -> http://rating-widget.com/
