Export supporting nesting/folders from Raindrop.io, in a format that maintains nesting when imported to Safari, FF, Brave, Edge, etc, Paid Pro users can import, and keep nest, I thought export should work as well...

I am a paid Raindrop.io Pro user, and I cannot import into Safari or Firefox, from a Raindrop.io Export, and see the nested bookmarks. Everything is flat. I feel I just paid and am now trapped to raindrop.io app, to view the nesting that I had in Safari.

Is (can there soon be) there a Pro export format that will preserve the nesting to Safari, Firefox, etc.? Thanks.

It seems the logic is somewhat known in order to successfully import with nesting intact.
