A customer shared access to a lucidchart document from their account containing different diagrams in several tabs. I am trying to export a copy of the document and upload it on our lucid account. I do not want to work on the customer’s original version, nor share it with other users. I need to create a copy and save it on our lucid account to make edits. I do not see options under Export to download it as lucidchart diagram or to import the document in our lucid account. If I export it as Vision, I am afraid I would need to rework the diagrams, which is not efficient. What’s the best option here?
