LuckPerms and MassiceCore Issue

[PierrEauBinet]

version of luckperms : v5.0.128
version of massivecore : 2.14.0
My server runs on 1.15.2 with spigot 1.15.2
When i play with luckperms without massivecore, my ranks are visbile in the chat with the prefix, colour etc... When i play with luckperms and massivecore, all my grades disappear from the chat but remain active. When someone talks in the chat, his pseudo his full white in this format message as if there was no luckperms plugin
My question is : how shall i configure my massive core plugin so that my luckperms are visible in the chat when someone talks, and in the same time have massive core and faction active ( i would like that when someone talks, we see his rank of luckperms and not the rank of the faction because on my server it would have less importance than the grades of luckperms) I hope sincerely that you will be able to help me because your faction plugin seems very great and i need it
