How can I get Jellyfin to read my NFO files?

[xre]

I've created some custom nfo files as jellyfin's metadata has some gaps I wanted filled in (mostly cast and crew information). However, I'm rather new to using both Jellyfin and NFOs in general so thus far my efforts have not been working. Jellyfin seems to just return the default metadata. 

When I created a new library (I just have 2 videos in there as a test) I unticked everything other than the box that said NFO. I presume that would be disabling the scrapers?
I created the NFO with Text Editor and ChatGPT since (literally asked it for a template for an NFO compatible with Jellyfin). I tried TinyMediaManager but most of the metadata was from IMDB and it wouldn't do IMDB. The CAPITALISED words are intended to be deleted and replaced with whatever the specific metadata is to be clear.

This is what it gave me:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<episodedetails>
<showtitle>TV SHOW NAME</showtitle>
<title>EPISODE NAME</title>
<epbookmark>OVERALL EPISODE NUMBER</epbookmark>
<season>SEASON NUMBER OR NAME</season>
<episode>EPISODE NUMBER</episode>
<aired>AIR DATE (YYYY-MM-DD)</aired>
<runtime>RUNTIME IN MINUTES</runtime>
<mpaa>RATING (e.g., TV-PG)</mpaa>
<rating>IMDB RATING (e.g., 7.5)</rating>
<plot>EPISODE SUMMARY</plot>
<actor>
<name>ACTOR NAME 1</name>
<role>CHARACTER NAME 1</role>
</actor>
<actor>
<name>ACTOR NAME 2</name>
<role>CHARACTER NAME 2</role>
</actor>
<crew>
<member>
<name>CREW MEMBER NAME 1</name>
<role>ROLE 1</role>
</member>
<member>
<name>CREW MEMBER NAME 2</name>
<role>ROLE 2</role>
</member>
</crew>
</episodedetails>



After I filled in the details I was told to just manually change the extension from txt to nfo.
What went wrong/Where do I go from here?
