Extend Get EventSub Subscriptions to lookup a single Sub by ID
Extend
https://dev.twitch.tv/docs/api/reference#get-eventsub-subscriptions
To add a optional query string param of id to allow developers to lookup a single subscription.
If a developer stores the ID's when the subs are created, they may want to spot check a single ID's status, or check the settings of it, without having to paginate or manually filter the results returned when using on of the currently offered filter options

Filtering by constraint could be great as well. So I could just lookup the subscriptions of a specific channel and remove them or edit them etc.

I like this idea!
Currently I need to paginate to 600K channel.follow events, to find a specific ID to check they status. This is not optimal and also consumes a lot of load and api limits.
