How does Embedding work?

So there are a lot of applications (Lark, Notion for example) that allow for embedding of Airtable tables into their site. I’m wondering if it would be possible to embed a SeaTable in place of the AirTable table using the same connector.

Further, the documentation on embedding states you just have to add the “-tag” to a hyperlink, but does that mean you just add it to the end of the hyperlink? And if so is there a list of applications where this would work?

You mean like on this page: https://www.seafile.com/en/roadmap/

Have a look in the source code of the page. All you need to do is to add an external link to an iframe.
