Hi,

I would like a variant of cite per the APA specification that removes the
bracket when quoted in mathematical definitions, theorems, etc. I could of
course do it manually for reach using right= and left= but I didn't want to
do it every time. I have come up with this MWE:

\startbuffer[ref]
@book{burago2022course,
  title={A course in metric geometry},
  author={Burago, Dmitri and Burago, Yuri and Ivanov, Sergei},
  volume={33},
  year={2022},
  publisher={American Mathematical Society}
}
\stopbuffer

\setupinteraction[state=start, color=blue]
\setupcolors[state=start]

\usebtxdataset[ref.buffer]

\usebtxdefinitions[apa]
\definebtx
    [apa:cite:theorem]
    [apa:cite]
\startsetups btx:apa:cite:theorem
    \btxflushauthorname{author}
    \btxcomma
    \btxflush{year}
    \fastsetup{btx:cite:righttext}
\stopsetups

\setupenumeration[
  before={\blank[medium]},
  after={\blank[medium]},
  alternative=serried,
  right=,
  headcommand=\groupedcommand{}{.},
  distance=0.5em,
  width=fit,
  headstyle=bold,
  titlestyle=bold,
  way=bytext,
  conversion=numbers,
  prefix=chapter,
  list=all,
  title=yes,
  indentnext=no,
]

\defineenumeration[definition][
  text=Defintion,
  style=normal,
  number=no,
]

\starttext

\startdefinition{\cite[righttext={{ p.\nbsp 1}},
alternative=theorem][burago2022course]}

This is something

\stopdefinition

\startsubject[title={References}]
    \placelistofpublications
\startsubject

\stoptext

The problem with this is that the citation is not interactive like it would
be if I used apa:cite:authoryear and just removed the parentheses in the
options. How do I get it to highlight blue and be interactive like the
default behaviour when you turn on interaction? Also this is probably
overkill so if there is a better way to achieve this...
