Found the answer to my own question in old posts here. (Thank you Matteo!)
I have added this code to the processAlgorithm() function:
```
context.addLayerToLoadOnCompletion(
f'{gpkg_fn}|layername=my_view',
context.LayerDetails(
name='my_view',
project=context.project()
)
)
```
Seems to work at least.

Hi developers,
I have created a processing algorithm in python that creates a new gpkg
database with a bunch of tables and views. One of the views can be
loaded as a polygon layer, which works fine when loaded manually.
How can I tell QGIS to load that view as a polygon layer when the
algorithm has finished? (I think it must be the same as telling the
layername to load from the geopackage)
So far, I have tried both QgsProcessingParameterFileDestination and
QgsProcessingParameterVectorDestination as output parameters without
much luck.
Hope anyone can help. Kind regards,
Raymond
