URL for Theme Folder

If I want to point to a file that’s located in my theme, what is the proper URL for that?

Example:
<a href="https://example.com/content/themes/theme_name/file.zip" target="_blank">Download</a>

/file.zip, should work. The content/themes/theme-name directory is an internal implementation detail and isn’t exposed anywhere

Thanks. I’ll give that a go.
