This is implemented in the app with the cmd to use being specified via an input param.
See [[#0x00021A04]].

The app uses cmd [[#0x00020000]] first. When u8 reply_x5 from that cmd is >=0x20, it proceeds to use cmd 0x00021A04. Otherwise, the following cmds are used, with the output being written to the output_struct: [[#0x00021104]] (output_struct+0x0), [[#0x00021204]] (output_struct+0x2), [[#0x00021304]] (output_struct+0x4).
Then, if any of the 16bit output fields in output_struct are set to 0xCAFE, a flag is set to 0x2 (same field used for invalid-CRC, which uses value 0x1 for that). Then this returns 0.
