Matrix Table conditional row formatting in Hierarchy

Hi Team,

We're using Matrix table with 3 hierarchical rows.

We would like to apply conditional formatting to make unbold Construction Finance, LAP-LRD, SB, CMG-Insti, SCF, and SME (highlighted in yellow) which is in second hierarchy. ie. to apply bold formatting only to specific rows of the 2nd hierarchy.

Kindly advise.
