Missing License key

My colleague purchased a herelink and CubePilot set for a drone project. I discovered that I need a license key but I cannot find one in the box nor on any of the stickers on the outside. I can send you the Product and Serial numbers and pictures. How would I get the right license key for this device?

Kind regards,

salut, elle est sur la facture ou appelle ton fournisseur.
j’en ai acheté aussi et le code est sur la facture.

Please contact your reseller for the key.

I am not the reseller of this unit but I have the same situation with a customer. I am a reseller. You are advising customers to contact the reseller and I’m wondering why?
Are we supposed to take pictures of all the boxes? I

Because we can verify where does the Herelink come from if it were resellers asking for the missing key through standard procedure.
