At the moment, importing diagrams from other sources have limited shape support.

Confluence Whiteboards currently just reconstruct the unsupported images and the diagrams usually need a lot of touching up after the fact. For example:

• rectangle shapes from Miro become rounded rectangles in Confluence Whiteboards
• The text from a shape in Miro is added as a separate textbox attached to the shape in Confluence Whiteboards, rather than being embedded as shape text
• Importing database shapes would need fixing after the import

It would be nice to support other shapes outside of the ones that come by default or custom shapes to make the import more seamless.
