Please help me!!!
There is no script call for that. You'll have to write your own script to do that: find all URLs and convert the found text to hyperlinks.
Thanks for this info, I've been searching for it to use in a batch convert, but only been getting the first URL fully converted when I use the URLtoHyperlinks.jsx.
Is it possible to edit the current URLtoHyperlinks.jsx to add the convert all bit (I'm currently trying to work this part out as I've never written a script before) and save it as another name?

No, that's not really possible. It's a complex script that depends on its user interface. You'll have to come up with your own conversion code.
Adobe implemented the Convert to Hyperlinks box as a script, rather than a plugin, so it is not scriptable.
Click on InDesign >> Plugin SDK >> 2020 >> Cross Platform
Note there is also a scripting SDK which would be the more logical location, but I'm indeed talking about the Plugin SDK.
Be warned that this is a 500 MB download.
In the archive, you'll find source/open/components/converturltohyperlink/ConvertURLToHyperlink.jsx and related files.
This has been around in the SDK since CS5 and steadily grown in size by 50%, so it is likely the current source for the feature. I did not further look at it.
