[How to apply a blur effect to picture under pen shape (poly art)]

Hi All,

 

I would like to use Affinity Photo to create some nice low ploy art.

In other software packages you draw some triangles and apply an average blur.

 

In attached image I have started to draw some triangles using the pen tool and grouped them above the image.

 

Please can someone help and advice if there is a way to apply a blur effect on the entire group which will affect the image underneath it. (Not the pen border).

 

Any help is much appreciated! Thank you.
