I was showing examples of all the queries I have tried. 

I add the table: 
ALTER SHARE local_new_2022 ADD TABLE `amplifydata_local_local`.`default`.`a3cfbc5bd7bc947eaa8526d48c77e1d39` AS `default`.`new_2022`;

then I try to remove the table with the alias: 
ALTER SHARE local_new_2022 REMOVE TABLE default.new_2022;


and it does not work. However, this query has worked for months up to this week.
