Adding a WFS layer to ArcGIS Online map

[geovision]

I was looking for a way to add a WFS to a map in ArcGIS Online. I found several other topics about this and I found that it was possible. But looking at https://doc.arcgis.com/en/arcgis-online/create-maps/add-layers-from-url.htm#ESRI_SECTION1_2DE3CF6906... I can see that the WFS needs to be in a geojson format. The WFS that I'm trying to add doesn't have that and it also had basic authentication. 

What I have done is I have added the WFS in ArcGIS Pro and published it to a webmap in my ArcGIS Online and it shows the features in the map. So far so good. What I'm wondering now is, will the data be automatically updated from the WFS as well? Because when I look at the map details under layers it does say WFS:

Could you please add the item from URL on the "My Content" page? This should prompt you for credentials as the service is secured. https://enterprise.arcgis.com/en/portal/latest/use/connect-secured-services.htm#:~:text=store%20the%...

Please be mindful of the supported security on OGC services:

Only WFS 2.0 needs to support GeoJSON outputs.

The data will be updated automatically from the WFS data source.
