in mxraph how to use drawio all shapes

[wenlongLei]

I am using mxClient.js on the web side. The xml returned by the backend is initialized through mxgraph's mxUtils.parseXml(xmlString), and some shapes cannot be displayed. How to use or inherit the shapes already implemented by drawio on the pure web side

I need to upgrade mxgraph version in flowcharting to display new shapes
