Triggering keyboard/mouse events anytime iOS

I frequently use my iPad to develop remotely in VSCode or prototype designs in Figma. This is currently all done in the browser. Given that many of these experiences rely heavily on the keyboard I was hoping there would be a solution to make a keyboard persistent on the screen, or at least a few hot keys.

Is it possible for me to develop an accessibility tool that could stay persistent on the screen? Perhaps something that would talk with assistive touch? Or is that in Apple’s no no square?
