Add to list button (plus)

Suppose a list I embed to my website. This add to list button is visible to all user allow any user to add anything.

I mean is this possible only admin/owner of list will able to view this button, I hope this question came earlier too.

In List Settings, you can turn off “Allow users to add items”. For help with this, please see:

Remember that this is a premium feature that is available to your free premium lists OR on all lists if you are a Pro subscriber.

With this turned off, you will still see the Add Item button when you are logged in as yourself. Others can’t see the Add Item functionality. You can open an incognito window to test.
