Laravel funtion lastInsertID is not supported by PDO driver

I am using Firebird and having the following error:

SQLSTATE[IM001]: Driver does not support this function: driver does not support lastInsertId()

I dig a bit on Laravel sources, and found this piece:

public function processInsertGetId(Builder $query, $sql, $values, $sequence = null)
{
    $query->getConnection()->insert($sql, $values);

    $id = $query->getConnection()->getPdo()->lastInsertId($sequence);

    return is_numeric($id) ? (int) $id : $id;

}

I wish to modify the approach to use "INSERT INTO TableName (Field1, Field2) values (Value1, Value2) RETURNING ID" that is the way to get the "last insert id" on Firebird

I dig a little more and found vendor/laravel/framework/src/Illuminate/Query/Processors/PostgresProcessor.php and saw it has a custom implementation for the same function

public function processInsertGetId(Builder $query, $sql, $values, $sequence = null)
{
    $connection = $query->getConnection();

    $connection->recordsHaveBeenModified();

    $result = $connection->selectFromWriteConnection($sql, $values)[0];

    $sequence = $sequence ?: 'id';

    $id = is_object($result) ? $result->{$sequence} : $result[$sequence];

    return is_numeric($id) ? (int) $id : $id;
}

I could not find documentation and samples on how to write custom Processors, I tried to duplicate the Postgres code on another file, searched for other files that references it and made a mimic for Firebird, but without success, I could not find even how to tell that Firebird has a custom processor.

I will be glad if someone has a better approach to solve the problem, or could point me out the documentation where I can learn how to code and configure a custom processor. I have searched a lot and found nothing
