The touch screen that comes with the Flashforge Adventurer 5M Pro appears to be more responsive if you use a a tablet pen. I designed a pen holder based on this spool holder design: https://www.thingiverse.com/thing:6286294. Alibre Atom was used to create this design. Printed at 0.2 mm layer height 15% infill.
