Action: export tag field as text on MacOS

On Windows, I can create as part of an action to have a tag field exported into a txt file via the "Export" action type. On MacOS, this option is unavailable, or at least I can't seem to find it. Is there something I'm missing or another way I might possibly be able to do this as part of an action?

Any suggestions or workarounds would be greatly appreciated!

Perhaps this thread gives an idea for an alternative approach:

Thanks for the suggestion. I did give that post a look beforehand, and it's not what I'm looking for. On Windows, I can have Mp3tag read a tag field and output that tag field into a text file. I do this as part of my audiobook library to have book descriptions in the m4b files placed alongside in a txt file. On mac that option doesn't seem to be available.

I'll keep looking for now
