Hi everyone!
There’s a similar plugin by our team: Instagram Feed widget - Free Website Instagram Widget (on the page you will find an online demo). This is a cool app to achieve better trust of your business among the customers, this app uses reviews from your clients (or you can write them yourself 
) in Instagram and show them as customers’ testimonials.
If you got interested, see the installation guide: How to add Testimonials Slider plugin to Webflow website. If you have any questions, do not hesitate to ask.
Hope it will help someone!
