You need to connect RGB to alpha, not alpha to alpha.

Ah got you thanks for the help Jussi!

I tried with various convolution filters and frequency separation, but found that a quick and easy method actually worked the best (in Resolve anyway). 

Apply the EdgeDetect plugin to node 02 (a corrector node added to the node graph and connected to the source input), adjust parameters to get your edge alpha, then pipe node 02 RGB output to your main stream (node 01) alpha input, and apply blur. This approach can be adapted to work with channels individually.

I've been trying to replicate this but can't see to get the alpha from node 02 to appear in node 01 after I've added the EdgeDetect. If I then go to blur node 01 it blurs the entire image, not just the edges. What am I missing?

I saw a brilliant tutorial for this created by Juan Melara, if you haven't seen his tutorials before they're well worth checking out.
