We did implement a V2 perfomrce collector, but are not adding it to options, is this correct?

[buenaflor]

it's a behaviour difference.

for transactions we add it to the options so we can manually trigger onSpanFinish and onSpanEnded via options.collector.onSpanFinished() but now that we use lifecycle callbacks we dont need to do that anymroe for spanv2 so we dont need to add it to the options

I'll refactor the static version to use lifeecycle callbacks as well

[buenaflor]

Would it make sense to use the abstraction InstrumentationSpan instead, or did the logic also change for v2?

I checked and probably not, this specific integration requires lots of concrete specific usages, the abstraction wouldn't help here
