Gmail API best way to retrieve message list with already included metadata

Question

I'm trying to retrieve gmail messages using Gmail API and Laravel's HTTP Facade.

I noticed that users.messages.list only returns the message's id and threadId, I understand they did this to make the retrieval faster.

The problem with this is that, In my use-case, I wanted to retrieve each message's payload>headers: name="From" and name="To" to get the sender and the receiver's email address and later group the result by receiver's email address.

Now, what I did was, Initially call the users.messages.list by using GET https://gmail.googleapis.com/gmail/v1/users/{userId}/messages. Now I have access to every message's id.

Next, I then loop through the list and create a new property called meta and store the return value of users.messages.get using GET https://gmail.googleapis.com/gmail/v1/users/{userId}/messages/{id}

My code looks like this:

$list = collect((Http::withToken($user->token)
        ->get('https://gmail.googleapis.com/gmail/v1/users/[email protected]/messages'))->json()); 

// $list returns {messages: [{id: 12313, threadId: 15151}, {id: 215151, threadId: 12778}, ...]}

$final_list = $list->map(function ($value) {
    $value['meta'] = Http::withToken($user->token)
                     ->get('https://gmail.googleapis.com/gmail/v1/users/[email protected]/messages/{$message_id}');
    return $value;
})

// $final list should return {messages: [{id: 12313, threadId: 15151, meta: {...}}, {id: 215151, threadId: 12778, meta: {...}}, ...]}

Now, with this approach gave me error saying:

Symfony\Component\ErrorHandler\Error\FatalError
Maximum execution time of 60 seconds exceeded

I undestand that it gives this error, because each messages contain base64 format of the email's body message. Making it very heavy. I can exclude the base64 from the payload by using metadata scope, BUT by doing this, I wont be able to specify the q query parameter filters.

My question is that, is there a way to only retrieve the metadata without using metadata in the auth scope?

OR

Are there any optimal way of achieving the same result(same in the $final_result sample result)?
