Search group TMR temporary keys that can be used with the TMR JWT.

Parameters

• tmrJWT TMR JWT to use.

• options Option to filter the search results.

• completionHandler A callback called after function execution. This callback take two arguments, an [SealdListedGroupTMRTemporaryKeys](SealdListedGroupTMRTemporaryKeys.md#class-sealdlistedgrouptmrtemporarykeys) instance containing the response, and a NSError* that indicates if any error occurred.

Convert a group TMR temporary key to become a group member.

Parameters

• groupId The Id of the group for which to convert a TMR key.
