We have a team that has been using the standalone LucidChart for years and now wants to bring all of their hundreds of diagrams into Confluence.
I've installed the LucidChart plugin into Confluence, and have two questions/issues.
First, is there any way to mass import all of our LucidChart files into Confluence? The only way I'm seeing right now to get diagrams in is to create a page and manually add a chart to it, which is going to take forever if we have to do it for 500+ diagrams.
Second, I tried to do a single addition, and although I'm our site-admin and space admin (and an admin of the LucidChart team), I get this error when trying to add the diagram:


What additional permissions do I need?
