Remove Branding from Embedded Reports - license costs

Hi Metabase team,

Thanks for the awesome product you have been building!

We are using metabase’s embedded feature in one of our products which will be used by our end customers. I read from another discussion that you allow removing “Powered by Metabase” branding from embedded questions if we buy a commercial/whitelabel license. Could you please let us know how much does it cost and how to go about buying one?
