By double-clicking on the Vector layer entry in the Inputs list, we can add an input field for the point layer. It's a good idea to use descriptive parameter names so that we can recognize which input comes first and which comes later in the model. It is also useful to restrict the Shape type field wherever appropriate. In our example, we restrict the input to Point layers. This will enable Processing to prefilter the available layers and present us with just the layers of the correct type:
Setting a parameter as Points with a Point geometry type
The second input that we need ...
