Adding direct or external links

[alensforu]

Hello markkuleinio,
Firstly, thank you for making this Netbox plugin !
I was hoping to use it to have submenus in my left panels using direct links to a specific netbox page, or an external page outside of my netbox instance.
For example, adding a menu item with a link to a saved filter, something like https://netboxinstance.comt/dcim/devices/?filter=my-devices.
But when adding this I get an error :
`https is not a registered namespace

Python version: 3.11.6
NetBox version: 4.0.3
Plugins:
netbox_device_support_plugin: 1.0.14
netbox_hello_world_page: 0.1
netbox_inventory: 2.0.1
netbox_lifecycle: 1.0.4
netbox_napalm_plugin: 0.3.0
netbox_topology_views: 4.1.0`

My navigation.py file is like this

`menuitem1 = PluginMenuItem(
# "hello_world" is defined in urls.py
link="https://instance.comt/dcim/devices/?filter=nyc-devices",
link_text="New York",
)
menuitem2 = PluginMenuItem(
# "hello_world" is defined in urls.py
link="https:///instance.com/dcim/devices/?filter=sea-devices",
link_text="Seattle",
)

menu = PluginMenu(
label="My Sites",
groups=(
("Global Site Links", (menuitem1,menuitem2,)),
),
# See the icons in https://pictogrammers.com/library/mdi/
# (remember to add the "mdi-" prefix)
icon_class="mdi mdi-earth",
)`

Would you be able to give me a hint about how to add this kind of links to the plugin ?
Thank you
