Imports an existing KYB applicant for a corporate from your own Sumsub account into Bakkt's Sumsub instance, using Sumsub's Reusable KYC feature. The share_token is generated in your Sumsub account against an already-verified company applicant and consumed here so the corporate does not have to redo verification. On success the corporate moves to KYB_PENDING. Utilization of this feature requires previous contact with Bakkt support to enable cross-account sharing in Sumsub.
