Command APDU info

CLA	INS	P1	P2	Lc	Data	Le
00	10	00	00	01	08	(absent)

The Ins byte (instruction) is 10, which is the byte for CTAPHID_CBOR. That means the command information is in a CBOR encoded structure in the Data.

The data consists of the CTAP Command Byte and the CBOR encoding of the command's parameters. In this case, the CTAP Command Byte is 08, which is the command "authenticatorGetNextAssertion". There are no command parameters.
