+/**
+ * [Joshen] JFYI I'd foresee a possible UX friction point here regarding S3 access key IDs and secret access keys
+ * - We'd allow users to select access key IDs via a dropdown here, but require a text input for secret access keys
+ * - Chances are most users wouldn't have the corresponding secret access key for the selected key ID at the top of their heads
+ * - So highly likely may have to default to "Create a new key" -> which from here they won't know the secret access key thereafter
+ * - And it'll end up just creating more keys for each destination
+ * Ideal scenario: Just select an access key ID, we then apply the secret access key in the PATCH request, so FE has no
+ * context of the secret access key at any point

-/**
- * [Joshen] JFYI I'd foresee a possible UX friction point here regarding S3 access key IDs and secret access keys
- * - We'd allow users to select access key IDs via a dropdown here, but require a text input for secret access keys
- * - Chances are most users wouldn't have the corresponding secret access key for the selected key ID at the top of their heads
- * - So highly likely may have to default to "Create a new key" -> which from here they won't know the secret access key thereafter
- * - And it'll end up just creating more keys for each destination
- * Ideal scenario: Just select an access key ID, we then apply the secret access key in the PATCH request, so FE has no
- * context of the secret access key at any point
