[QGIS-Developer] Loading layer from specific table/view after running algorithm

[Raymond Nijssen]

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.
