Well, there is no markdown support at all :) So what happens comes out as a
result of trying to extract links out of plaintext. This in turn is handled
by the django urlize filter:
https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#urlize

Thus:

>>> from django.utils.html import urlize
>>> urlize('[call for papers](https://2022.nordicpgday.org/cfp/)')
'[call for <a href="http://papers](https://2022.nordicpgday.org/cfp/
)">papers](https://2022.nordicpgday.org/cfp/)</a>'

And I'm not sure they *should* be considered, since the mime type of the
body isn't markdown...
