how to make multiple custom animations with geckolib

hey . so i recently got into mcreator and geckolib . i know how to work with blockbench and i have already made my model with some animations . but i dont know how to add multiple animations like a second attack or a third attack . or maybe like a rage state . i thinks it can be done by using procedures . but i have no idea how to use that . i've seen some tutarials and they all have the block [play animation "animation name" ] . but for me it a number instead of the "animation name " and i can't replace the number with a text block .

sorry if it sounds too obvious or maybe complicated . i'm new to mcreator
