That ought to be a nice waste of the weekend. Spending several hours on something that can be summed up in about a minute sounds more like a poverty or hardship working on the congregation and harvesting spiritual energy for the purpose of allowing reptilian monsters to ruin life on our earth than any real information. I would simply not go at all, and if you must go, disregard everything you hear therein. They want more donations, start donating nothing. They want more field circus, stop going at all. They want people to go to boasting sessions despite Wuhan Flu or H5N1/H5N8, start letting the slightest tiredness be an excuse to miss one. They want you to quit your job to pious-sneer, and your job is decent, keep the job and cut back on field circus.
Or, perhaps now is a good time to stock up on things you keep. Food is a good place to start these days, with China under lockdown (such will create shortages, virus or none). Or, perhaps you need to assess whether or not you have the basic tools (common screwdrivers, an adjustable wrench, and a good set of pliers is the bare minimum). Maybe that washtowel donation money could go into silver or gold. And, you might wish to start buying a few sun-worship decorations now before the Chinese shortage hits--by next fall, it could well be too late.
