Post Hoc test for Fisher's exact test

[Curtains White]

Hello everyone! I have performed a Fisher's exact test (5X3 tables) and I have found statistically significant differences in my groups. How can I find out in which groups significant differences were found? Is there any post hoc test I can perform?
Thank you deeply in advance!

A bunch of pairwise Fisher's exact tests, though if you want to report those data you may want to think about correcting you alpha (level of significance) value.
