recording mouse movement while recording videos

How could you record the cursor movement in your videos. I mean that as the cursor movement recorded you could use it as pointer while not drawing.
I am suffering that the cursor just disappear in the record once then pen touches the drawing tablet. even this happens only when activate the (mouse mood) in the tablet software which makes bad affects on using the pen.
am a teacher and use Khan Academy as reference. I also provide online classes so that I try to record some videos. this problem happens whatever the drawing software is (PowerPoint, MS whiteboard or any other software) and whatever the recording software (Bandicam, Screencast o matic or recording a zoom meeting or any other recording app) nobody gave me an answer so that I hope that you don't mind telling me such secret :)
