MetaData Format for locally Imported Podcasts?

Support
1

I tried to convert some Amazon Originals to m4a and import the results into AntennaPod.
I also used mp3 files from a private podcast
The cover image doesn’t appear on the overview of the podcast and its episodes.
Just when playing the file.
Also there seems to be no proper episode number and no real release date for the episode.
In addition to that i would expect what vlc shows as “comments” to be part of the “Shownotes” section

Which fields in m4a and mp3 metadata are read and how are they mapped to a podcasts detailed view?

Currently, local podcasts use the embedded cover image as episode cover, the title, and the file modification date. Place a file called Folder.png in the local folder to get a podcast cover image. Other metadata fields are not read.
