How do I use externals on OS Catalina as it says there from an unidentified developer?

externals-in-catalina

I'm not on Catalina yet, but i'm curious if this works:

Try right-clicking on the external to open it with Max. When prompted for trust, answer in the affirmative.

After that, perhaps loading the external normally will work from then on without having to right-click.... let us know back here if the right-click trick works for externals(i didn't even think externals might run into this issue, sounds like Catalina has much tighter security than ever before :p).
