JS scripting error "undefined has no such function "persist""

This thread has been helpful, but…

How can I tell which openhab-js addon version was included in OH version 3.4.4?

console.info('openhab-js version: ’ + utils.OPENHAB_JS_VERSION);

doesn’t work in 3.4.4 (undefined)

console.info('OHRT version: ’ + helpers.OHRT_VERSION);

doesn’t work either (no helpers)

dumpObject() shows a history object and not persistence

I’d like to update openhab-js to a version that’s compatible with the documentation but in order to do that safely I need to know where I’m starting from.
