How to connect elements form different simscape sub-libraries?

Question

Specifically, my group is working on thermal modeling of EVs i.e cabin cooling and battery cooling. We have used most elements from the two-phase-fluid sub-library of simscape. But at two connections we want a controlled separation of the refrigerant flow. For that, there is an element called flow divider but it's in the hydraulics sub-library. So how do I use these libraries simultaneously? I'm trying since yesterday but nothings seem to work. Thank you.
