How to model Fracture Flow in Contact pairs, a coupled HM model

Dear all,
I plan to model hydraulic fracturing processes by using the cohesive zone model (CZM). CZM is available under the subnode "Contact" in the Solid mechanics module, but does not involve the fluid flow process. I found the "Fracture Flow" interface can be applied on the contact pairs, but it always causes some unexcepted issues. In the equation view, I found a "Lagrange multipier for pressure" is added in the depended variables when I applied "Fracture flow" on "Contact pairs". Now I cannot figure out how the fracture flow works in the contact pairs. And there is no Help document for this specific issue. Could you please give me some ideas? Thank you so much for your help.
