Lldb: how to call a function from a specific library / structure

Problem. In the project, we have localization functions that are specific to the framework / dynamic library. That is, they have the same name, but they extract resources from different packages / folders.

I would like to call a function from a specific library, something similar to:

lldb> p my_audio_engine.framework::GetL10nString( stringId );
lldb> expr --shlib my_audio_engine.framework -- GetL10nString();
lldb> p my_audio_engine`L10N_Utils::GetString(40000)

but all of these options do not work.

Adding gdb to tags, hoping the same if semantics exist, will also work on lldb.

In parser lldb expressions

lldb is currently not the equivalent of gdb foo.c :: function meta-symbol to encode a function from a specific source file.
