Fluid as a portal igniter?

Hi! I'm new on McCreator and i wanted to create a custom dimension... and i did that... except for the fact that i have no idea how to set a fluid block as a custom igniter... I tried using the "Make a portal to a dimension using custom igniter item" Built-In procedure, but i just dont understand how to do it, unfortunately i dont have time to check the forum so will you please be so kind to text me on Discord? My username is "vol_pane", just send me a friend request and ill accept, please someone respond, ive been searching for 3 days now!
