Unable to close PasswordContainerView

[matelo]

When PasswordContainerView is opened, I am not able to close it on user demand. There is no Cancel/Close button (only delete)
I suggest to add Close button (for example on the left of 0 ), or add new method to PasswordInputCompleteProtocol -
func passwordInputClose(_ passwordContainerView: PasswordContainerView)

This can be fired when DELETE button is tapped on empty input, in guard statement of deleteInputString
