Does OOB Legal Request external storage with Google Drive work with Shared Drives?

[mpsteve137]

I am working on setting up an integration between Legal Request Management and Google Drive to have documentation stored externally. There is native OOB functionality that supports this integration. However, I was given a Shared Google Drive to set this up with. The all the OOB subflows, mainly 'Legal External Storage Core - Google Drive' and 'Legal External Storage Core (Permission) - Google Drive' use the deprecated Google Drive Spoke actions that DO NOT allow for including Shared Drives. So, unless I am missing something, it would appear this integration does not support Shared Drives, but I cannot find any documentation that explicitly says this. Can anyone help me confirm please?
OOB:

No option to include shared drives in the action the OOB subflow calls, so it will not find them:

Thanks for any help

OOB Legal Request + Google Drive Spoke is built for My Drive. Shared Drives usually fail with Folder ID not found or HTTP 405 until the Drive API is told to include them.

On the spoke REST steps that create/copy files or folders, add supportsAllDrives=true on the resource path (Google Drive API v3 files.*). Repeat on every action that touches the Shared Drive, not only Create Folder.

The integration account must be a member of that Shared Drive. Drive.file scope is often not enough for Shared Drives; you typically need a broader Drive scope your Google admin will accept.

After that, test one Legal Request with a known Shared Drive folder ID before pointing the Legal storage config at it. If Legal Request Management has no toggle for Shared Drives, the spoke change is the fix, not the Legal catalog itself.

So basically I would need to customize a lot of OOB logic to make it work with shared-drives?

nah not a lot of legal oob. just the google drive spoke, add supportsAllDrives=true on the create/copy actions and the integration user has to be in that shared drive. legal catalog can stay
