How to make sql nested/sub query in PHP - php

Question

I'm struggling with implementing SQL query into my php code.
The query:
select template_id, min(created_at) as created_at from (
select distinct
root_template_id as template_id,
date_created as created_at,
response_id as response_id
from db.score
inner join db.users ON db.score.supplier_id = db.users.old_id
inner join db.acc ON db.acc.user_id = db.users.id
where db.acc.account_id = 25) as T
group by template_id
I was able to prepare only this part:
$query = DB::table('score')
->selectRaw('DISTINCT root_template_id as template_id, date_created as created_at, response_id')
->join('users', 'score.supplier_id', '=', 'users.old_id')
->join('acc', 'acc.user_id', '=', 'users.id')
->whereIn('acc.account_id', $request->id)
And it works, but it is only responsible for the nested part, for the subquery if I can call it like this. Can someone share any thoughts?

DB::table() usually receive table name as a string, but it can also receive Closure or an Illuminate\Database\Query\Builder instance, so this should do the trick for Laravel's select from subquery:
DB::table(function ($query) use ($request) {
$query->selectRaw('DISTINCT root_template_id as template_id, date_created as created_at, response_id')
->from('score')
->join('users', 'score.supplier_id', '=', 'users.old_id')
->join('acc', 'acc.user_id', '=', 'users.id')
->whereIn('acc.account_id', $request->id)
}, 'T')
->select([
'template_id',
DB::raw("MIN(created_at) AS created_at"),
])
->groupBy('template_id')
->get();
