Here are the HTML tags and CSS that intercom’s API supports for Articles - https://developers.intercom.com/docs/guides/help-center/supported-html
I don’t see callout blocks and collapsible sections which are supported in Intercom’s editor.
When I use the API to update my articles (update article endpoint), even if I send the exact CSS that intercom uses for the callout blocks and collapsible sections, it strips them out as those are not on the allowed list. These articles then get published without the callout blocks that were present earlier.
How can I preserve callout blocks and collapsible sections? It is a major limitation towards using the API.
