Hi @Anil Lande 

"Having only ' sn_hr_le.activity_writer' is not sufficient to edit HR Templates. Users with role 'sn_hr_le.activity_writer' can only edit templates where user is member of the group which is populated in owned by field on template."    ---> that's what I'm trying to achieve, maybe I missed that information in my post.

I already have a group that will be managing some particular HR templates, and in HR Template will use Owning group field populated with this group.

I want to allow members of that group to manage (edit) those templates only.

As far as I understand this role (sn_hr_le.activity_writer) is required to have in Group, if I want to allow agents to edit templates, correct?
