Counts min and max quantity of equals 'strings' based on a filter column

[RIC63]

Good morning


in Excel 2021


I need to count the minimum and maximum quantity of duplicate strings in J9:J70 according to the value in column H


So in the attached example a formula placed in K3 should return 6, in L3 11, in M3 2 and in N3 9


...I don't know how to modify the formula I put in K3...


Thanks if anyone can help me
