Hello, I’m new at this forum, I have been trying to find the right answer for this question but I can’t find it. So the idea is, I’ve made a custom keyboard for mathematical operations such as Integrals and Matrix and all , so I’ve downloaded recently an app “Mathway” I hope you know it , where you can write for example integral and it gives you access to write on integral sides.

So my question is how I can add these numbers on top of integrals or matrix …
