How to use the @api-platform/api-doc-parser/lib/swagger/parseSwaggerDocumentation function in @api-platform/api-doc-parser

const parser = entrypointWithSlash => {
  const options = {};
  if (program.username && program.password) {
    const encoded = Buffer.from(
      `${program.username}:${program.password}`
    ).toString("base64");
    options.headers = new Headers();
    options.headers.set("Authorization", `Basic ${encoded}`);
  }
  switch (program.format) {
    case "swagger":
      return parseSwaggerDocumentation(entrypointWithSlash);
    case "openapi3":
      return parseOpenApi3Documentation(entrypointWithSlash);
    default:
      return parseHydraDocumentation(entrypointWithSlash, options);
  }
};
