laravel complex query building with join and groupBy - php

Question

I am new to laravel and have the following query in core PHP that needs to be laravel query.
$query="select distinct(c.c_id), 1 'companyToken',c.companyname,u.email,creation_date,CONCAT(eu.firstname,' ',eu.lastname) 'Name' , group_concat(pk.package_name) 'Package Name/Service' , c.notes 'Notes' , c.demo_status 'Demo Status' from ee_company c
left join et_company_payment_methods cpm on cpm.c_id=c.c_id
left join et_packages pk on cpm.package_id = pk.id
inner join (SELECT *
FROM `ee_users`
WHERE c_id IS NOT NULL
GROUP BY c_id) u on u.c_id=c.c_id
left join ee_users eu on eu.id=c.referred_by_user_id
group by c.c_id";
i am just getting started with laravel so finding it difficult to convert such a complex query.
the existing system works fine with this query.
i tried building it with laravel.
$company = DB::table('ee_company')
->leftJoin('et_company_payment_methods', 'ee_company.c_id' , '=', 'et_company_payment_methods.c_id')
->leftJoin('et_packages', 'et_packages.id', '=', 'et_company_payment_methods.package_id')
->join('ee_users',function($join){
$join->on('ee_company.c_id', '=', 'ee_users.c_id')
->whereNotNull('ee_users.c_id')
->groupBy('ee_users.c_id');
})
->leftJoin('ee_users', 'ee_users.id', '=', 'ee_company.referred_by_user_id')
->groupBy('ee_company.c_id');
it gives me following error
Call to undefined method Illuminate\Database\Query\JoinClause::groupBy()

Try this one
$company = DB::table('ee_company')
->leftJoin('et_company_payment_methods', 'ee_company.c_id' , '=', 'et_company_payment_methods.c_id')
->leftJoin('et_packages', 'et_packages.id', '=','et_company_payment_methods.package_id')
->join(DB::raw('SELECT *
FROM `ee_users`
WHERE c_id IS NOT NULL
GROUP BY c_id'),function($join){
$join->on('u.c_id', '=', 'c.c_id');
})
->leftJoin('ee_users', 'ee_users.id', '=', 'ee_company.referred_by_user_id')
->groupBy('ee_company.c_id');
