[Feature Request]: html embedding / iframe support

[harrismcc]

Description

It would be so amazing to be able to embed iframe content into documents, and this is really the big "missing piece" for me with AFFiNE at the moment. I often am writing documentation for developers where I'd want to embed a code sandbox, or video (hosted online, not a local file or YouTube).

Notion currently has this functionality, and it's something that so far seems exclusive to Notion for whatever reason.

Use case

• Embedding code, like from codesandbox
• Videos from many platforms
• Could be used to integrate w/ other tools, like embedding a status dashboard directly into a document

Anything else?
