Hi , i was request this option in WPLMS4
https://wplms.io/support/forums/topic/helpdesk-add-course-student-can-see-private-replies-option/
for some reason(helpdesk topic create can't put under unit content even just put helpdesk button to redirect、unit will redirect bbpress shortcode when submit or click next page), we may go back to use WPLMS3, so any possible can add option in WPLMS3
if yes, can WPLMS team can offer custom code for it, thanks.
Checked for the solution from custom code so that we can do this thing but Currently, it can not be done
