I've tried both https://github.com/toriihq/gatsby-plugin-intercom-spa and https://github.com/search?q=gatsby-plugin-intercom to try to integrate Intercom but have been unsuccessful.
The README for both these plugins state that I merely have to install the plugin via npm (in my case I use yarn add) and then update gatsby-config.js
with the relevant code snippet (and use my Intercom app_id).
Are there other steps that need to be taken care of?
