Best way to reheat chicken and dumplings?

No instructions from the caterer/store which provided the dish?
If yes, they should know best.
If no, I would take the dumplings off the top and eat aside..
Heat the stew part (chicken, veg, gravy) covered, so as to warm through but not burn the bottom of the pot. Mw, stovetop, oven, instant pot or whatever.
Check at intervals, stir to promote thorough warming and no burning.
Don't add broth from the start, but only if/as it seems to be needed, for desired thickness of stew.
When nicely hot and boiling, put dumplings on top, cover, warm a few minutes until heated through and serve.
Enjoy your party!

To add to my question, I was thinking about reheating over stop top and adding more chicken broth to ensure it has enough liquid. I am thinking the dumpling may soak up most of the broth it was prepared with. Someone please help! I don't want to ruin the dish. Thanks in advance!
