about ceph-mgr

Hi dev, Nice to meet you I want to modify the code from ceph dashboard I try to modify the code from /usr/lib/ceph/mgr/dashboard/frontend, but the web do noting even I delete all frontend folder. I guess the frontend should built to the /frontend/dist folder by angular or nodejs; however, both of the methods is failed. Can you tell me how to build or run the frontend code I modify to the web? Thank you very much Best regards Hausiowen Nayu
