如何在Chrome中撤消持久存储？

Question

要使用this

来实现chrome持久化存储

if (navigator.storage && navigator.storage.persist) navigator.storage.persist()
.then(granted => {
    if (granted) console.log("Storage will not be cleared except by explicit user action");
    else console.log("Storage may be cleared by the UA under storage pressure.");
});

但是如何以编程方式删除PERSISTANCE？
