magento2 – Requisition Lists- How to enable and share out-of-box in Magento 2 Cloud

Had a question on requisition List. Some users are able to see the requisition list and for some it is hidden. I am aware there is an “enable” configuration for Requisition List at Website level(General -> B2B Features’)

a) If some users do not see the Req. List, does it mean that the config is disabled for their website or is there some other configuration?
b) If out-of-box, user wants to share his Requisition List with other users in the company, is there such a feature, if yes, how would we do that?
