When using BR Restore to TiDB Cloud prompt it will prompt warning "privilege check for 'Update' fail"

Question

When using BR Restore SQL to restore data to TiDB Cloud , it will prompt warning messages: "privilege check for 'Update' fail". However, it will not prompt warning information if I restore data to OP TiDB.
For example:

The data of table has been restored to TiDB Cloud . In tidb.log ,I just find the follow information. So I need to know the reason for the warning messages.

The error is that br wants to update mysql.stats_meta table to update snapshot, count columns of restored table by sql and the tidb returns error of privilege. Please use sql of SHOW GRANTS; to check whether your user has privilege of update for mysql database. And this error doesn't influence the result of restore, because it only updates the statistics information.
