How do you do when plastering around windows?

[bellman83]

I have gaps of 10-15 mm around the windows, the frame is in lightweight concrete.
Outside will be plastered with Sto and inside with some gypsum mortar.

I am going to purchase the materials for this.

For the outside, Sto has given me a specification of what I should use, but I am unsure about the inside.

How do you handle the gap around the window? It's stuffed, but should the plaster be applied directly onto the reveal against the frame and then with sufficient thickness, or how is it done?

How do you handle the gap around the window? It's already wedged, but should the plaster be applied directly to the casing in the reveal and then in sufficient thickness, or how is it done?

You build out the reveal so it extends onto the window.
