-\* The `SUPPRESS_EMBEDS` flag can be both set and unset, while the `IS_COMPONENTS_V2` flag can only be set. When the `IS_COMPONENTS_V2` flag is set, any of the used `content`, `embeds`, `sticker_ids`, `files[n]` or `poll` values in the initial message must be set to `null` first, otherwise it will fail with a 400 BAD REQUEST response.
+\* The `SUPPRESS_EMBEDS` flag can be both set and unset, while the `IS_COMPONENTS_V2` flag can only be set. When the `IS_COMPONENTS_V2` flag is set, any of the used `content`, `embeds`, `sticker_ids`, or `poll` fields must have their values reset to empty. For `content` and `poll` this is `null`. For `embeds` and `sticker_ids` this is `[]`. Failing to do this will result in a 400 BAD REQUEST response.
