In the minehut console you go to at https://minehut.com/dashboard/appearance and then you should see an area that says "server command" in that area type "op (yournamehere)" and then press enter.
So i want to make a factions server but the is no 1.7 TNT mechanics plugins so it makes raiding TRASHH. I was wondering if you could add a 1.7 TNT Mechanics plugin? Potentially this one: https://www.spigotmc.org/resources/1-7-1-12-1-better-tnt-mechanics-%C2%BB-added-the-old-mechanics-of-tnt.46788/
