// *** Request Verification ***
// The currently recommended way is to verify request signature: https://api.slack.com/authentication/verifying-requests-from-slack
// Unfortunately, GAS web apps don"t have means to access request headers. Thus, this example uses the old way to verify requests.
// >>> Settings > Basic Information > App Credentials > Verification Token
const legacyVerificationToken = PropertiesService.getScriptProperties().getProperty("SLACK_VERIFICATION_TOKEN");
// *** OAuth Access Token ***
// Install your Slack app into its development workspace.
// >>> Settings > Install App > Bot User OAuth Access Token
const token = PropertiesService.getScriptProperties().getProperty("SLACK_BOT_TOKEN");
