Should the outer reveal be plastered when using compriband?

Hello everyone,

since the exterior wall of the existing building is not 100% vertical, I have a gap of 5mm between the door and the wall at the bottom of the terrace door and almost 1.5cm at the top edge.
It is sealed with compressible sealing tape.
Do you have a suggestion on how I can plaster the exterior reveal so that it remains vapor permeable on the outside?

Lime-cement plaster is generally purely mineral and vapor-permeable, making it ideal for plastering your window reveal.

Attach the facing strip with sealing cord and then plaster with lime-cement plaster.

Yes, that is most effective this way. This way you can also straighten the slanted wall.
