Look at the requests in the inspector, next routing passes along the data in the header:
next-router-state-tree:
%5B%22%22%2C%7B%22children%22%3A%5B%22view%22%2C%7B%22children%22%3A%5B%5B%22id%22%2C%221b0c4494-0899-4bb5-b6c9-66cdbbc23ad0%22%2C%22d%22%5D%2C%7B%22children%22%3A%5B%22__PAGE__%22%2C%7B%7D%2C%22%2Fview%2F1b0c4494-0899-4bb5-b6c9-66cdbbc23ad0%233ZHX%2F64lX9TrTx5KI1hgMrJzdgbwoRcHTQBxpcYbBQc%3D%22%2C%22refresh%22%5D%7D%5D%7D%5D%7D%2Cnull%2Cnull%2Ctrue%5D
which decodes to
["",{"children":["view",{"children":[["id","1b0c4494-0899-4bb5-b6c9-66cdbbc23ad0","d"],{"children":["__PAGE__",{},"/view/1b0c4494-0899-4bb5-b6c9-66cdbbc23ad0#3ZHX/64lX9TrTx5KI1hgMrJzdgbwoRcHTQBxpcYbBQc=","refresh"]}]}]},null,null,true]
which includes your resource and decryption key.
