Is it possible to add the Fira Code ligatures to another font mainly the infinite length part of it and if so how?

[iCraft85]

I just wanted to know if its possible to add infinite length ligatures of Fira Code to other fonts. I have tried using something like this https://github.com/ToxicFrog/Ligaturizer but it doesn't work and seems like the repo has been inactive for a while. So is there any alternative or manual way to do this?

Would want to know that as well
