First, create a document or find the link of a document.

For example the document is hm://z6MkgisVMELvqnsCo3dYmtVpy8PiqPGMVwfAyBWFn84vebq4/seed-developers/web-development

yarn web:prod && yarn web:start

Now go to http://localhost:3000/hm/z6MkgisVMELvqnsCo3dYmtVpy8PiqPGMVwfAyBWFn84vebq4/seed-developers/web-development
