How to write NDEF record that is readable on NFC Tools?

I'm having trouble writing an NDEF record that can be read via NFC Tools or Taginfo.  I can read the record on the Proxmark 3 RDV4 via the "nfc type4a read" command.  I've been changing settings and digging at this for hours.  I don't know what I'm missing.  Any suggestions?

Here are the following commands I'm using:

hf mfdes formatpicc

hf mfdes createapp --aid 000001 --fid E110 --dfhex D2760000850101 --numkeys 01

hf mfdes createfile --aid 000001 --fid 01 --isofid E103 --amode plain --size 00000F --rrights free --wrights free --rwrights free --chrights free -m plain --no-auth

hf mfdes createfile --aid 000001 --fid 02 --isofid E104 --amode plain --size 0007D0 --rrights free --wrights free --rwrights free --chrights free -m plain --no-auth
		
hf mfdes write --aid 000001 --fid 01 -d 000F20003B00340406E10400FF00FF -m plain

hf mfdes write --aid 000001 --fid 02 -d 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 -m plain
