Will it be possible to use weights in GDS Betweenness Centrality?

Dear Neo4j team,

Can you add the option to use weights in GDS Betweenness Centrality

or

is it possible to extend the library by myself and how to do it ?

Thanks in advance for your reply

Betweenness centrality doesn't currently support weights, but it's on our backlog!

Our code is open source, if you want to extend it

Hello
Kindly do you update the Betweenness Centrality to take weights into consideration?
Many thanks
