Need help with power analysis GPower Novice

Hello everyone. I am doing a power test for Fishers Exact Test on GPower, and dont know how to determine the proportions p1 and p2. I have 2 categories that im looking at if there is a difference between one and other across 4 rows. How would i calculate the P1 and P2 for this.

Basically i have the data completed and the analysis ran for the tests but need to determine if I actually had enough power to detect a significant effect.

Thanks in advance for the help.
