I stucked while adding new permissions to customUsers. I hope you can help me to solve it

I stucked while adding new permissions to customUsers

I'm trying to add several permissions Some of them are saving without any problem. Any errors aren't raising when I give permissions, but I'm not being able to add these perms only. Nothing else

(
        ('can_view_socialmedia', "Can view socialmedia"),
        ('can_add_socialmedia', 'Can add socialmedia'),
        ('can_change_socialmedia', 'Can change socialmedia'),
)

to my adminstrator model but I stucked. After that I tried to add those conflict permissions by django signal. But nothing changed. I don't know why I can't add these permissions

Note! I already did makemigrations and migrate commands

Here you can see my code belong to giving permissions to users 👇👇👇
