I'm aware that Lightroom Classic allows users to watermark photos on export. But is there a way to watermark RAW photos synced on the cloud? Imagine that I'm using the Lightroom photos as a gallery by itself for the public or embedded into Adobe Portfolio and since photos are not being passed through the export process, I have no method to watermark them.
The only way I am aware of is to export to jpegs with watermarks, reimport those and share those to a Lightroom or portfolio gallery. Or use a solution like smugmug or similar instead which supports watermarking.
