-- Returns bot information as follows:
--
--
--     * If you provide the @nameContains@ field, the response includes information for the @> LATEST@ version of all bots whose name contains the specified string.
--
--     * If you don't specify the @nameContains@ field, the operation returns information about the @> LATEST@ version of all of your bots.

-- This operation requires permission for the @lex:GetBots@ action.
