Hi @Mohammed-Skouti, You can try below code snippet; it's working fine for me.

Node collectionNode;
if (assetNode.hasNode("jcr:content/comments")) {
    collectionNode = assetNode.getNode("jcr:content/comments");
} else {
    collectionNode = assetNode.addNode("jcr:content/comments");
    collectionNode.setPrimaryType("nt:unstructured");
    collectionNode.addMixin( "mix:lastModified");
    collectionNode.setProperty(
        "sling:resourceType", "granite/comments/components/collection");
}

Node commentNode = collectionNode.addNode("customComment");
commentNode.setPrimaryType("nt:unstructured");
commentNode.addMixin( "mix:lastModified");
commentNode.setProperty("sling:resourceType", "granite/comments/components/comment");
commentNode.setProperty("jcr:description", "Your Comment Here");

session.save();
