Creating a folder within an existing bucket - eg on DigitalOcean Spaces

I was trying to find out how to create a folder in an existing bucket and came across the problem mentioned in this thread. Creating a folder may be related to the issue raised in the thread, in which case I’ll wait for this to be resolved, but it may not be related.

If I want to create a new folder, and then use the S3 Multi Upload Control component to upload files to that folder, is the only way to use the S3 Put File server action? At this point, I just want to create a folder, without uploading any files (so I would have to upload a dummy file in order to create the folder).
