Compilation error of example Storage list

[DaGigabyte]

I'm trying to compile the following example in platformio. https://github.com/mobizt/FirebaseClient/blob/main/examples/Storage/Sync/List/List.ino

src/main.cpp: In function 'void setup()':
src/main.cpp:110:13: error: 'using AsyncClient = class AsyncClientClass' {aka 'class AsyncClientClass'} has no member named 'setAsyncResult'; did you mean 'returnResult'?
     aClient.setAsyncResult(aResult_no_callback);
             ^~~~~~~~~~~~~~
             returnResult

I encountered the above error when compiling. Is there some missing dependency that I'm not aware of? Or is there something flawed with the example code?

Please read the library documentation first.

Library compilation is fine from many platforms compilation test.

You library installation or your board library installation is not complete.
