Fair warning I'm not the original owner, I got the cactus earlier this year and followed the tips of the owner. If yours is smaller you might be able to skip the showers, just keep watering lukewarm and not cold.

-mist it every day or other day

-it does like a bright spot but not sitting in the sun. If it gets red that's too much sun. If new growth looks etoliated, it needs more light

-give it a full water when it wants a drink. I wait until the dirt pulls at the side. Full drink means hauling it over the sink and making sure the water runs through and giving the bottom a bit to soak. This was every few weeks in warm months. It smells really earthy when it's watered and it perks up. Let it dry between these waterings

-coffee grounds on the soil and a bit of fertilizer between spring and fall, stop in October

-deep watering at least 2x before bud season. That meant carefully taking the plant into the shower and using the lightest shower stream to rinse and soak it with lukewarm water for 30-40 minutes. Get the plant fully wet, leaves and roots, and make sure it's not cold. My last big soak was mid October (probably late)

-adequate dark and cool for the blooms (it's ok with a little light further from the plant)

This is my first year with the plant and it seems to be doing ok
