Have you tried cbor.me?
Do you mean display in text like:
[1, h'1745', "2001003ffe3ff805aa16ed2392f6f0cbI", 1725840060, 1751414340,
[], 10,
h'26FD3A734B3366FFE4AB68DBD2230812FD0B197090BA1EAA7EB34FFA38FFB78F', [-3,
[7, h'2001003FFE3FF805AA28CD1AE2A3DAE3']], 12,
h'C839BEEB65370B7E815BCA24585288E7EB8ACD2A490B5E80640BA4822AE905BC4734B8AE267738913E7CB729C8192A754887E4115178FCD878A2C19F91670109']
Or do you mean more expanded like:
