I used official Facebook documentation (https://developers.facebook.com/docs/marketing-api/conversions-api/parameters/customer-information-parameters) to add external id parameter, but it is only visible in Facebook Events Manager (Test events).
In Events deduplication it is shown as 0% sent (Conversion API however, has no problem with this parameter detection).
What am I doing wrong?

Try using this package, it will help to simplify tracking using a Facebook Pixel. It also supports multiple pixel Ids. https://www.npmjs.com/package/ngx-multi-pixel
I hope it helps.
OK it seems that external id need to be added as an advanced matching parameter, in the third parameter object of the
fbq('init', XXX, {external_id : "HERE"})
method.But it won’t appear in the Test Event tool as mentionned in the doc
