I have made a simple example to show how one can do this perhaps - I am used to working with the element-nodal force vectors when designing saying connections so that is the udr I have used as shown below. We can then export the results to excel and sum the element nodal force to obtain the total reaction which -100 N as shown, and is as expected equal and opposite to the applied load which is 100 N in this example. I think as shown it can be done also with ENFOY.
Should be said here, that mesh is fully compatible at the intersection of the two plates so no contacts - if we have contacts then we can get the reaction at the contact with a contact/force reaction probe (under the force reaction probe we can choose to look at the contact region).

Hope this helps
