find X,Y position in PDF by a specific text.

[luiswback]

Hello everyone, how are you? I would like to know if there is any way to obtain the x and y position of a PDF by passing text.
For example, I want to get the position of the text “XPTO” on each page.

I need this because I'm working with signatures and some documents have a default position to be signed and I need to obtain that position using an existing PDF providing the text in that position to sign in the correct place.
Can anyone help me with this? I've seen some old issues that said this feature could be implemented in the future, but I can't find a solution.
I'm working with angular 11.
Thanks everyone.
