That's probably ok then. :)
A screenshot is not a proof as the info can be trivially forged in devtools. The original author should post the permission on some personal page e.g. on the info page of the original script.
Turns out this proof is sufficient (until the original authors themselves make a report) per the clarification in https://greasyfork.org/en/discussions/moderators/95094
@wOxxOm I think kakasearch(another author of this modified version) asked for the permission just in greasyfork, and maybe you can check their conversation. If he/she didn't do this in gf but in other platforms(like an email), I'll ask the original author again for permission. Thank you.
The original script didn't set license. This means "do not distribute", did you get explicit rights to reuse that code? https://greasyfork.org/en/scripts/391736-elegant-alert
