Removing part of ceiling joist for HVAC Unit

I am not a framing expert but have some limited knowledge. I need to create a 23" x 23" joist bay in my kitchen ceiling to house an HVAC ceiling cassette. Assuming the joists are 16" OC, after cutting out the appropriate length of the middle joist, what is the best method to support each end of the cut joist? Does code typically require a double cross brace at each end or just a single? What is the best way to attach the brace to the end of the cut joist? What is the best way to attach the cross brace to the full joists on each side while minimizing the need to remove drywall bigger than the opening? Thanks.

If its just one ceiling joist... you just need to head it iff to the adjacent joints, using joist hangers. 6 of them in all.

Thanks. That's what I thought.
