AFAIK, mu4e doesn't use the compat library (yet) since you cannot
install it from ELPA or some other archive anyhow given that it's
tightly coupled to mu mail indexer, i.e., the C++ and the elisp parts
must be compatible.

No, no.  I've meant that with substitute-command-keys I have the correct
key-descriptions in the buffer with help-key-binding face.  However, I
would also like to have them clickable so I think I need to "parse" the
buffer and add keymap properties to the text having the help-key-binding
face.

So for example, there is the text "[j]ump to some maildir" where the j
is a key-description (recognizable by its help-key-binding face), I need
to translate back the j to the command mu4e-search-maildir in order to
add a keymap where RET and mouse-2 are bound to that command.
