It expects base64 encoded PKCS#7, not binary though. Note that in _https://datatracker.ietf.org/doc/draft-ietf-ace-coap-est/_ we assume all cert payloads are binary.

https://tools.ietf.org/html/rfc7231#appendix-A from June 2014 makes it all very plain. However, there is a small problem of running code.

There's already an erratum: https://www.rfc-editor.org/errata/eid5107

For whatever reason, it is sitting in state "reported" since 2017.
