Laravel Livewire - Property type not supported in Livewire for property: [{"withTimestamps":false}]

I've been trying to set up a many-to-many pivot table between meetings and attendees. When I try to call the relationship function in MeetingForm.php

$this->attendees = $meeting->attendees();

I get the following error

Property type not supported in Livewire for property: [{"withTimestamps":false}]

I've tried also including timestamps in my migration but it makes no difference and I'd rather not have to include them, is there a way around this or is it not possible to do what I want to do?

Attendee.php

     *
     * @var array<int, string>
     */
    protected $fillable = ['name', 'email'];

    /**
     * Get the meetings for the attendee.
     *
     * @return BelongsToMany
     */
    public function meetings(): BelongsToMany
    {
        return $this->belongsToMany(Meeting::class);
    }

    protected $fillable = ['title', 'meeting_time', 'status'];

    /**

     *

    {
        return [
            'status' => MeetingStatus::class,
        ];
    }
