Defer a non-asset file

Hello,
I want to defer third-party codes to improve my site speed, and I came across a few solutions but they all say to use this line . But what if the file I want to defer isn’t in the assets file. I tried to defer the files that impact my site speed, and it gives me this message:

So my question is, what should we replace “asset_url” with? since it doesn’t exist in the assets folder?
