I want to use the old clock applet in the MATE panel, instead of the clock in the indicator applet. Therefore, I don't want Ayatana indicator to display the time.
I disabled "Enable this Indicator on login" for the Date and Time entry in Ayatana Indicator settings, but it continues to show the time.
I am using Ubuntu MATE 22.04.
