How to create a global trigger

I am new to modding in general, and I have always been intimidated by it because I don’t know Java, but I heard about Mcreator and how you could make mods without code, so I tried it. I successfully made a few keybinds, but I had trouble with one of them. I am very familiar with command blocks and I wrote a single command that gives you telekinesis. I plugged it into Mcreator and found it only does it once. Normally I would just use a repeating command block, but that obviously doesn’t work. I tried solving it anyway I could, but I hit a wall. I found a repeat block in Mcreator that didn’t work. I finally came across someone with a similar problem on the forums, but I need to create a global trigger, and I have no idea how to do that. I made the global variable, and coded it so it checks if the variable is true, but I have no idea how to create a global trigger
