Urgent: Cannot read static files in Vault Application

I want to add custom json or txt file and want to parse some value from the file on runtime. But unfortunately, I am unable to parse the value. VAF cannot find the directory:

Code Example:

string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "sample.txt");
string data = File.ReadAllText(path);

Error:

The system cannot find the file specified. (Could not find file 'C:\Program Files\M-Files\23.4.12528.8\Bin\x64\sample.txt'.) (0x80070002)
(M-Files 23.4.12528.8 2023-05-17T09:12:15.029Z)

Observation:

In normal c# application, the base directory should point to where the build file of the application is. But in VAF, it is pointing to where M-Files is installed on my machine.

Thanks.
