Hi @Omer_Katz,
Thanks for reaching out to our community!
Looking internally, it looks like we don't currently support this with our S3 integration, but we have a bug request on file to look into this further. I can post here if we make any progress on getting this to work with the integration!
It may be possible to connect to your resource with our Rest api integration in the meantime. It looks like we have some users trying that here
Let us know if that will work for you for now!
