First time EK trip - connecting via LAX (on AS). And so, here goes with a few Qs.

It looks like the LAX lounge has reopened. Can someone please confirm? (And where is it?)

I assume I will need to see a real EK agent at some point for doc check verification (passport, PCR test results, etc.) no matter what AS has done or issued @ SFO. Correct?

Can this occur in the Lounge? (I wouldn't want to wait until the gate opens should there be any sort of issue).

I would like to avoid a landside adventure if possible. But if that is not possible, does EK F provide any sort of expedited or private-ish TSA security experience?

How likely is hand luggage to be weighed?

Thanks!
