OSC-route does not work in Max standalone without Max file associations in Info.plist

[aarushbothra]

Using MacOS Ventura 13.3 with Max 8.6 and the latest release of CNMAT-Externs for x86-64 Macs (running in rosetta on an M1 mac).

When using OSC-route in a standalone .app file, the Info.plist file that is generated when Max builds the external works because it has the file associations for Max files included in the Info.plist (this is the "Document types" entry in the .plist file). However, when using a custom .plist without these file associations, OSC-route refuses to load into my standalone, even though other externals work fine and the OSC-route external files are included in the .app.
