Merging words together animation

Hi guys I am new to webflow and this is my first post so I apologize if anything is missing. I am designing my first Portfolio website. Looking at some tutorials I came across this awesome animation of words changing like merging with each other: Five Years of -99 design studio
I am not too sure but I believe this has some custom code, but after some research, I was unable to find anything, could you please enlighten me if someone knows. Thank you

PS: Where it says “I AM RICARDO” I would like to have the same animation and change “I AM CREATIVE” “I AM INNOVATIVE” etc
