Recursive module.exports

In a NodeJS 14+ project main JS, how can I recursively export all .hbs files?

Tried:

module.exports = () => ({
   partial : __dirname + "/../partial/**.hbs",
   helper  : __dirname + "/../helper/*.js"
});

This seems to work:

module.exports = () => ({
   partial : __dirname + "/../partial/**/*.hbs",
   helper  : __dirname + "/../helper/*.js"
});
