Can't select text. Limitation of the underlying Pdfium library?

[HubKing]

I think selecting and copying text is an essential feature of a PDF viewer. I had tried another C# Pdfium control that was deprecated in 2017, but most web search results were referring to. It did not have text selection. It only had "Get Text" button. I downloaded this control and it was the same: I could not select text, and only "Get Text" is available.

So..., is this the limitation that comes from Google's Pdfium library itself and there is no easy way to add text selection?
