How to create an infoblock or an inscription in Bitrix, visible only to the moderator?

Answer 1

1) If the moderator is an administrator, then
a)

global $USER;
if ($USER->IsAdmin())
{
    //надпись
}

b) in the settings of the infoblock, make access only to the administrator
2) If the moderator is a certain user from a certain group, then:
a) check whether the current user belongs to a group, for example, with id = 3

if ( CSite::InGroup( [3] ) )
{
    //надпись
}

b) the same only for group 3
