Can't delete Sharepoint folders created by Microsoft Graph API but can delete ones created in web browser

Question

I can delete files and folders created directly in SharePoint and Teams via web browser or desktop app.

But when I create a folder via Microsoft Graph API, the delete option is not shown in the drop down menu in the web browser or desktop app, and when I try to delete that folder using the Microsoft Graph API I get a 403 Error (a permission issue, I believe).

I'm an owner of the team/site with read and write permissions.

Here's the API info used to create the folder:

POST /groups/{group-id}/drive/items/{parent-item-id}/children

BODY

{
    "name": "1 Proposal",
    "folder": { },
    "@microsoft.graph.conflictBehavior": "rename"
}

And the one to delete:

DELETE /groups/{group-id}/drive/items/{item-id}

Is there something I should put in the body when creating the folder to help with permissions (inherited from parent folder or something)?
