[SOLVED] ShowDetail function habilitation

Hello,

I need to make available button ShowDetail for specific user (Allow user to find user in list with search option, even if user not already in project)
Concerning field is idContact from activity form (by example)

Only admin as this right at this moment, but i don't understand how permit it to other users
NB : Concerned field is idMenu:72
although i allow update from non-project habilitation, he can't acceed to this functionnality

I don't understand link between habilitation and accessright. Accessright is modified by update on non-project habilitation screen, but not habilitation (table).

non-project habilitation screen


Table habilitation


Table accessright
