Where are these QuickViews in the interface?

While trying to add help-urls to the built-in plugins registries, I discovered 3 quickviews that I cannot guess how to access. There aren’t corresponding categories where a Context Menu can be raised.

One is in a category=CATEGORY_QR_DATE and the other 2 are in category=CATEGORY_QR_MISC.

# ------------------------------------------------------------------------
#
# Age on Date
#
# ------------------------------------------------------------------------

register(
    QUICKREPORT,
    id="ageondate",
    name=_("Age on Date"),
    description=_("Display people and ages on a particular date"),
    version="1.0",
    gramps_target_version=MODULE_VERSION,
    status=STABLE,
    fname="ageondate.py",
    authors=["Douglas Blank"],
    authors_email=["dblank@cs.brynmawr.edu"],
    category=CATEGORY_QR_DATE,
    runfunc="run",
    help_url = _(""),
)

# ------------------------------------------------------------------------
#
# Filter
#
# ------------------------------------------------------------------------

register(
    QUICKREPORT,
    id="filterbyname",
    name=_("Filter"),
    description=_("Display filtered data"),
    version="1.0",
    gramps_target_version=MODULE_VERSION,
    status=STABLE,
    fname="filterbyname.py",
    authors=["Douglas Blank"],
    authors_email=["dblank@cs.brynmawr.edu"],
    category=CATEGORY_QR_MISC,
    runfunc="run",
    help_url = _(""),
)

# ------------------------------------------------------------------------
#
# Attribute Match
#
# ------------------------------------------------------------------------

register(
    QUICKREPORT,
    id="attribute_match",
    name=_("Attribute Match"),
    description=_("Display people with same attribute."),
    version="1.0",
    gramps_target_version=MODULE_VERSION,
    status=STABLE,
    fname="attributematch.py",
    authors=["Douglas Blank"],
    authors_email=["dblank@cs.brynmawr.edu"],
    category=CATEGORY_QR_MISC,
    runfunc="run",
    help_url = _(""),
