有没有一种方法可以编辑Twilio节点模块的config.json文件，以便它为sms-twilio节点显式设置Account SID和Auth Token。我可以通过编辑flow.json文件来实现吗？
按照twilio模块README.MD文件的指示，我尝试编辑twilio节点的config.json以合并我的帐户SID和Auth令牌，但是当我运行node-red时，我仍然得到相同的“客户端需要明确设置一个帐户SID和验证令牌”。

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

这是config.json文件，应该提供所需的SID和Auth令牌。
//Configuration for running tests and examples against the Twilio API
module.exports = {
accountSid:'**************************', // Actual Json isnt "*"'s
authToken:'***************************',
from:'*********', //The Twilio number you've bought or configured
to:'************' //The number you would like to send messages to for testing
};
