Connecting Amplitude to Front for Product Insights

I am currently exploring options to connect external services not currently available in Front. We are aware of Front´s metric and analytic capabilities but will still need a bridge or integration. The application in question is Amplitude.

Since there isn't a native integration or plugin, I’m curious how others are doing this. For those of you who have moved past Zapier/Make and into Custom Plugins, was it difficult to set up the connection?
