Regexp Patterns for Modal Input Fields

[Walledgarden]

👋 Hey there!

I'm recently creating an app which has a function, which allows users to build embeds using Select Menus and Modals (An embed preview with a select menu with the editable options). While doing that, I realized, that it would be very helpful if I could register Slash Commands and their Options with a Regex Field, which should allow us, to show a customized error message, if the Regex isn't met (either via a gateway event or hard-coded in the Slash Command Registration process). For example, this functionality would make it easier, to check if users follow a certain pattern for color codes (/^\#[\dA-Fa-f]{6}$/) and avoid the needless step, to show an ephemeral error and opening the embed again with being required to fill in the values again.

I strongly believe, that there are a lot of other use cases for this feature, feel free to comment them below!

Thanks for reading though, I'd love to hear your opinion about this!
