Hi @Engineer
We are using a GUI-based packaging tool called "Packages" to create the .pkg file.
I extracted the signed pkg file to check distribution.xml, here are the contents from the file:
<?xml version="1.0" encoding="UTF-8"?>
<installer-gui-script authoringTool="Packages" authoringToolVersion="1.2.10" authoringToolBuild="732" minSpecVersion="1.0">
<options hostArchitectures="x86_64"/>
<!--+==========================+

<title>DISTRIBUTION_TITLE</title>
<background file="background" uti="public.png" scaling="proportional" alignment="bottomleft"/>
<background-darkAqua file="background" uti="public.png" scaling="proportional" alignment="bottomleft"/>

<choice id="installer_choice_1" title="app title" description="">

</choice>
<!--+==========================+

<pkg-ref id="app_bundle_id" version="22.11.0" auth="Root" installKBytes="563402">#app.pkg</pkg-ref>
<pkg-ref id="app_bundle_id">

<app id="app_bundle_id"/>
</must-close>
</pkg-ref>
</installer-gui-script>
