How you enable cloud storage options for your users depends on what type of account you have:
For "Launchpad" accounts, the cloud storage options are set at the account level on the account properties page. If you have Super Admin access via Frame Platform Unlimited, you can do this yourself. If you do not have this access, you can simply submit a support request and our support team will configure this for you.
For Frame Platform accounts that only have the embedded player option for sharing apps (no Launchpad), you can set the cloud storage options in the session settings section in your dashboard
