Developer Instance: Manage Extensibility item missed for Data Admin and I can't add LTI 1.3 Tool Provider to check my tool. Is it okay?
 

It seems that DevCoPDataAdmin has no permissions to do that. Maybe there is some other way how I can add my LTI 1.3 tool to the dev instance? Please, advice. Thank you!1
