mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces

[itvexesme]

Whem I'm running backup.sh, at some point it says about issue for mysqldump with message:
mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces
I'm using $webserver_user set as www-data.
I also tried various ways of running /usr/share/php/passbolt/bin/cake passbolt mysql_export --dir ./ <username> directly, with
root and app sql account user (set during installation of passbolt) - the result is the same.

I have Passbolt 4.6.0 on Ubuntu 22.04.

I'm aware of losing information from Passbolt database required for correct backup creation with this issue.
Can you check it or advise about this issue?

Below you can find complete log from backup.sh:
