 Args:
   id: string, The ID of the raster collection to which these rasters belong. (required)
-  modifiedAfter: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been modified at or after this time.
+  modifiedBefore: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been modified at or before this time.
+  creatorEmail: string, An email address representing a user. Returned assets that have been created by the user associated with the provided email address.
   pageToken: string, The continuation token, used to page through large result sets. To get the next page of results, set this parameter to the value of nextPageToken from the previous response.
+  role: string, The role parameter indicates that the response should only contain assets where the current user has the specified level of access.
+    Allowed values
+      owner - The user can read, write and administer the asset.
+      reader - The user can read the asset.
+      writer - The user can read and write the asset.
   createdAfter: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been created at or after this time.
   tags: string, A comma separated list of tags. Returned assets will contain all the tags from the list.

-  createdBefore: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been created at or before this time.
   bbox: string, A bounding box, expressed as "west,south,east,north". If set, only assets which intersect this bounding box will be returned.
-  creatorEmail: string, An email address representing a user. Returned assets that have been created by the user associated with the provided email address.
-  modifiedBefore: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been modified at or before this time.
+  modifiedAfter: string, An RFC 3339 formatted date-time value (e.g. 1970-01-01T00:00:00Z). Returned assets will have been modified at or after this time.
