Perform manual code review on a part of the application (GitHub, Gerrit...) + Run static analysis tool and review reported bugs (SonarCloud, SpotBugs, VS Code Analyzer, Codacy, Coverity Scan...).
As the tools can find a lot of bugs and warnings, it is enough to review a subset of them and if all team members agree, fix them. Make an effort to examine different types of bug reports, preferably non-trivial ones.
