As part of a similar idea, see https://community.sdl.com/ideas/tridion-ideas/i/tridion-sites-ideas/workflow-approvals
We moved start/finish workflow buttons under "Activity" details section and above "Related items" section
This should give a possibility for Editors not to be blocked by new notifications that might appear
It is also possible to turn off workflow related notifications per Content Manager instance, however not a specific user group
Although it will hide also "Things To Do" panel in the top right corner in user callout
