Question

When i exported my game with godot to web, and when i run it on mobile it opened on-screen keyboard automatically. And nowadays i have a C++ project and i am exporting it to web using Emscripten. And when i open it in my phone on web it doesn’t open on-screen keyboard. I just wonder that how does Godot’s Web export opens keyboard?
