Read binary file located in project directory using @ionic/react-hooks/filesystem

Hi guys. I want to read a docx file inside my src in runtime. this is my function:

const loadTemplate = async (readFile) => {
  try {
    let contents = await readFile({
      path: "./template.docx",
      directory: FilesystemDirectory.Data
      //encoding: FilesystemEncoding.UTF8
    });
    console.log(contents);
    return contents;
  } catch (e) {
    throw e;
  }
};

readFile function is destructed from useFilesystem() destructed from ‘@ionic/react-hooks/filesystem’.
it says Error: File does not exist.
How can I open binary file located in my project?
