Thanks, patch applied with the following modifications:
js file name should be "row_security_policy.js" instead of "row_security_policies.js".
Node name should be "row_security_policy" instead of "row_level_policies". Node name should not be pluralized and it matches the folder name.
Icon name should be "coll-row_security_policy.svg" and "row_security_policy.svg", it should matches with the Node name.
The 'Owner' should be renamed to 'Role' and there must be a role 'public' in the drop-down list. If the user does not provide any role then by default it is public.
Keywords like select, where, As should be in upper case in Jinja template.
The policy node is disappeared when updating any value. Fixed that issue.
There is no icon showing after creating the RLS node.
