Hi @dianadianathales,
We added the ability to link S3-compatible storage in a recent release, so you can link DigitalOcean Spaces via the Amazon S3 link. :Desktop and Web Releases (10-30-2018) Win v.6415 / Mac v.6470
For the “HOST” parameter you would use the [region].digitaloceanspaces.com. For example, sfo2.digitaloceanspaces.com
