Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

The automatic suspend notifications were getting annoying.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

An attempt to disable power notifications was made on a fresh install of Debian Buster and does not seem to be effective.

   * What was the outcome of this action?

Power notifications are still shown, even after rebooting the entire system.

   * What outcome did you expect instead?

I expected to not see power notifications anymore.
