Localized tool labels in LTI dynamic registration

[JacobTh]

I can’t find any information in the Canvas documentation about using localized labels with dynamic registration. The Canvas docs reference the 1EdTech Dynamic Registration specification, which states that localized label representations may be included as described in Section 2.1 of the OIDC-Reg specification.

According to that specification, language tags can be added to client metadata member names, separated by a # character, for example

{ 
  "client_name": "My Example",
  "client_name#ja-Jpan-JP": "クライアント名",
}

However, I haven’t been able to get this to work in Canvas when adding my tool via dynamic registration. Am I missing something in the documentation, or has anyone successfully implemented this in Canvas?
