Might be a duplicate of Non-games on the Discord Store but I felt like requesting it in a more in-depth way and with features that aren't mentioned before.
For Example: As a Discord bot developer you have to send people to an external service to let them donate to you or maybe upgrade to enable paid features which I'm pretty sure some developers want some kind of support to as with a bot like a music-bot, hosting can become rather expensive with large bots.
Such functionality to a store-page in a guild or a page that could be triggered with a link or a button click (which would be possible to be added in a future update to bots which is already planned) would be nice as you won't have to let people leave the app, which would be more safe for the end user and lower the gap of financially supporting the developer as well.
This of-course could fall under the existing Developer License but it would be nice to use the now deprecated Games Store for something like this.
This would help a lot monetizing applications on Discord instead of only applications that would run outside of the app and better support Developers overall.
