The enter's default behavior is different on IOS and Android

when I disable the Enter keymap which is from the ‘baseKeymap’, the behavior is confusing. On Android, it acts like on PC,enter cannt work but on IOS, PM will create a new paragraph and insert a br tag. I dont want this behavior on IOS, how can I fix it?

Don’t disable the Enter keybinding. If you don’t bind something, you’ll get the native behavior, which may differ across platforms.
