Is there a pdf editor that's able to open files with a password for opening/reading, save with password, delete and add pages?

I tried LibreOffice Draw. With Draw it’s possible to delete pages and export as Pdf and set passwords.

Btw Draw isn’t displayed in the apps menu (9 dots).

LibreOffice Writer=>click lower x to close the unsaved document=>Draw Drawing=>File=>Export as=>Export as PDF=>tab Security=>Set passwords=>enter your passwords=>click OK=>click Export

I didn’t try to add pages but I suppose that it works, too.
