Customize edge color based on node selection Holoviews/Bokeh Chord diagram

I have created a holoviews chord plot where each node is associated with particular group(community). I have a requirement that whenever I tap on a particular node all the edge associated with it should be same color as the color of the node.
For example in this chord diagram If I select a blue node the edge color should be same as node color(i.e blue).

But here


when I click on a blue node I am getting few edges of of blue and few edges of orange color(basically the edge takes the color of it’s source node). Is there any way to customize the color of the edges depending upon the node selection? I can see few options available for the edge_selection_line_color like field, attr, value etc but could not figure out how to use this for customizing the edge color like my requirement. I am sure that it is fairly easy task but could not figure out how to achieve and I am stuck in it. Also let me know if it is possible using bokeh CustomJS . when I click on a blue node I am getting few edges of of blue and few edges of orange color(basically the edge takes the color of it’s source node).

@philippjfr any suggestion would be highly appreciated.
