BelongsToMany::using() method not working well

[Ashk2a]

• Laravel Version: 8.70.2
• PHP Version: 8.0
• Database Driver & Version: MariaDB latest & MySQL 8

Description:

BelongsToMany::using() method not totally works. Work fine on create but not when I want get the collection through the relation.

I've two connections named website (default connection) and auth.

Steps To Reproduce:

Models :

• User.php (website)
• Account.php (auth)

Pivot :

• UserAccount (website)

Service using the relation User->accounts :

• AuthService

So when i want create a new record everything work ! But when i want to get the collection $user->accounts the using looks ignored..

I've this error : (trying to use the model Account connection and not the pivot connection)
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'auth.user_accounts' doesn't exist

Also I'm forced to precise the table in the belongsToMany cause the attribute $table in Pivot is ignored..

    /**
     * @return BelongsToMany
     */
    public function accounts(): BelongsToMany
    {
        return $this->belongsToMany(Account::class, 'user_accounts')
            ->using(UserAccount::class)
            ->withTimestamps();
    }
