F5 Venafi Solution for Enterprise Key and Certificate Management

​Looking to get some help with this integration.  I have followed the directions to a tee.  Question is this.  When the F5 BIGIQ submits the request to Venafi for a certificate, we usually have an approval workflow set up in Venafi and it may take up to an hour for someone to approve the certificate.  How will the F5 BigIQ handle this scenario?  Is it expecting an immediate response from the Venafi API or will it wait an check in?  Need some better documentation on this.  We also have our Venafi policy folders set to not allow users to submit their own. CSRS, we want the keys to be stored in Venafi.  But in this case the BIG IP is submitting the CSR/key.  How will it handle that?  Any help is appreciated.
