[RPG] How does D&D 5e handle group skill checks


I have looked at the Lost Mine of Phandelver and see many times where a skill check for wisdom is vital, I want to get my group to work together, like everyone contributing and cooperating, instead of having the guy with the highest skill mod take the lead every time.

Thus, I come to the conclusion that I want to put in a group skill check system of some kind. I saw a few people mentioning in past editions about their way:

All PC rolls, person with highest value will be the one to pass that check.

This seems alright, but I didn't know if it fits with this edition.

I also thought it would make sense if another character could help with the search and give him an advantage on the check. 2 is better than one right? Thematically, everyone would help search.

The problem I have is that many traps, among other things require the PC to actively search. Unless, I am allowed to yell at them to make a wisdom check prior to the trap?

So how does DnD 5e handle group skill checks? Are there rules for this kind of thing already? Or does anyone have any tried and tested house rules that they've implemented?

The reason I'm asking is because the 5 PC in my campaigns have pretty low Wis, max of 12.

Rules for group checks in DnD 5e can be found on page 59 of the player's basic rules or page 175 of the PHB and are as follows:

To make a group ability check, everyone in the group makes the ability check. If at least half the group succeeds, the whole group succeeds. Otherwise, the group fails.
