[FEATURE] Discord - integrate instant triggers with custom app/bot token

Currently PipeDream supports 2 Discord components, Discord app and Discord bot, with 2 different actions and triggers.
The issue is that, if you need triggers and/or actions from the both of them, you have to integrate 2 bots/apps in the server, which is not really... convenient.

For example, I need instant triggers such as "New Message (Instant)" and these are not available through Discord Bot in PipeDream, but only through the Discord App in PipeDream, so it means that in every server we would have to grant access to our bot AND to pipedream bot for a complete workflow (as the Discord bot already uses our bot token).
PipeDream should allow the use of our bot token through setting the oauth redirect url in the Oauth settings in the Discord Developer portal. At least, that 's a solution other providers have implemented. And that's the way it was implemented in V1 from what I've seen in old videos.
Or the trigger for instant actions could be ported to the Discord bot, as this one already integrates the bot token/app and the API.

**Is your feature request related to a problem? Please describe.**
We can't deploy 2 bots for one app in clients discords especially bots from different sources (one named pipedream the other differently)
