Search on hidden meta custom fields 2

Hello, I have the same problem as teamf (@teamf) 3 years ago, his ticket is https://www.ads-software.com/support/topic/search-on-hidden-meta-custom-fields/ .

I don’t see my hidden meta key _podcast_show in the list of meta keys.

And in general, the plugin does not show any hidden meta key on the site.

How to fix this issue?

Plugin version 2.1.1 , downloaded yesterday November 3, 2022 from WordPress org
