where EjMostrarB is the name of a GeoGebra Text Object. The code works perfectly on the installed version, but it does nothing online (running under windows 10, with chrome, firefox and edge).
This is the link to the applet: https://www.geogebra.org/m/qztwmfsu
The signalled button is supposed to copy the text inside the yellow rectangle to the clipboard, but it does not work online.
Could anyone help me solve it? Thank you.
