Constant naming conflict with Download Monitor

I am currently using Debug Log Manager 2.3.6 and Download Monitor 5.0.33 with WordPress 6.8.2.

When I update Debug Log Manager to version 2.4.2 I get this fatal error :

Fatal error: Uncaught Error: Call to undefined function dbDelta() in /Users/nico/Local Sites/dIm/app/public/wp-content/plugins/download-monitor/src/Installer.php: 189 Stack trace: #0

If instead I update Download Monitor to version 5.1.3, I get these warnings :

Warning: Constant DLM_VERSION already defined in /Users/nico/Local Sites/dlm/app/public/wp-content/plugins/download-monitor/download-monitor.php on line 37
Warning: Constant DLM_URL already defined in /Users/nico/Local Sites/dlm/app/public/wp-content/plugins/download-monitor/download-monitor.php on line 42

I suspect both plugins are using the same constants which create a conflict.
