Problem freehand digitizing with stylus

[Jipforester]

Hello everyone,

As part of my job, I have to digitize maps in the field. I want to use the freehand digitizing function with a stylus to draw my lines and polygons, however the icon located under topological editing does not appear even though I am using a stylus. When I connect the mouse it works, I can activate the freehand digitizing icon and draw with one click but not with the stylus. I use the Blackview Active 8 Pro tablet with a stylus without a battery. Do you think it is necessary to have an active stylus (with battery) or no ? Has someone achieved to solve this problem ?

Thank you in advance for reading my request. I noticed this question has been asked before but it's from a while ago.
