Hi @XavierDagassan-9764 ,
Thanks for reaching out.
As far as I know, unfortunately, there is currently no graph API to get Yammer Community conversation details using MS graph. Based on my research and testing, we can only fetch the below reports from Yammer using MS Graph.
More information for reference:

Hope this helps.
