Help to add contrib-roam2.el to spacemacs

[Standinocw]

Very like below config for org-roam. How to add the settings to org layer?
org-roam-node-display-template
(format "${doom-hierarchy:*} %s %s"
(propertize "${doom-type:12}" 'face 'font-lock-keyword-face)
(propertize "${doom-tags:42}" 'face '(:inherit org-tag :box nil)))
