Need help with FFMpeg install and finding correct file

Hi All,
I just received the error message that asks me to install FFMpeg. It has been rather frustrating because the Audacity interface led me to believe it was something that could be easily fixed with a ‘click here to download’ type of thing. Instead, I am led to an FAQ type page and caught in a loop, trying to find a download link. Ready to pull my hair out.
I am running Mojave 10.14.6 and have Audacity 2.3.3. The message tells me that I need a file named: ffmpeg.55.64bit.dylib However, after downloading and unzipping a number of FFMpeg packages, I can find no file under that name.
What am I doing wrong? Where can I download the proper file? Many thanks!

From this page:
Click on the link that says: RECOMMENDED download:ffmpeg_64bit_osx.pkg
Then follow the rest of the instructions here to install it: Installing FFmpeg for Mac - Audacity Manual

Thank you, I appreciate it!
