Is it possible to upload an icon for a workspace while creating a workspace through create_workspace?

I’m creating workspaces through the API and everything works fine. But what I want to do next is also upload the icon to a workspace. Is that possible?

My current code is:

mutation {{
        create_workspace (name: "{organisationID}", kind: open ) {{
            id
        }}
    }}

Thanks already for your help!

Best,
Nick
