Are you sure he might not have meant during mass?
During communion, quite often the priest will bless those who don’t receive, such as children or those who can’t consume gluten. From my understanding this is an actual blessing and the Extraordinary Ministers of Holy Communion should not be performing a blessing during Communion.
I remember someone questioned and apologist about the Extraordinary Ministers giving a blessing and to clarify his point he jokingly said well someone can go up to them if they want but keep in mind they’re shooting blanks.
I agree with @Lee1 on this. We have the “authority” (and are commanded in James 5) to pray for and over anyone. If touching the person, on the head or legs, helps you both get deeper in pray then go for it. As long as you both realize that all healing comes from God and on your own you are just “shooting blanks” I think it is admirable to pray for and over someone who is suffering.
Keep up the good work,
