Welcome to the Audacity Bootcamp Podcast. The noise gate in Audacity version 3.0.0 doesn't work. It's broken. It looks like it works, but it doesn't. There's a promised fix pending in the upcoming version 3.0.1 but until then, there is no noise gate in 3.0.0.
If there's an upside, it's that the Attack Time has been separated out from the Decay Time. In previous versions, the Attack/Decay time was bundled together in one setting. In this new version, they have been separated out and each can be adjusted independent of the another. Plus, the Attack time can now be set as low at 1ms. Previously, it could only go as low as 10ms. This is a great enhancement for the noise gate. Now we just need it to work.
I have a video illustrating this that shows this setting change and how you can tell the noise gate doesn't work in 3.0.0. Here's the link if you would like to watch it.
