Embedding Content within a Collection Entity

I have a client who has a significant amount of content that needs to be contained within a Webflow CMS site.

Part of that content is a non-Youtube/Vimeo video that is usually contained within an Embed.

I can’t see a method by which an embed code block can be inserted into a collection entity at all. How can I achieve this? When I post a simple link to the video, it doesn’t work, and I can’t see any way to insert an arbitrary video embed block within the collection editor.

Any help is appreciated.

You can embed custom code in a code block placed inside a Rich Text Field which is part of the CMS collection. The WF University has details.
