A fatal error occurred headmap session recording

Hey team
I have upgraded Headmapsessionrecoding plugin and after that i am getting error when going to fetch recording.

A fatal error occurred

The following error just broke Matomo (v4.13.3):

Call to undefined function Piwik\Plugins\DevicesDetection\getBrowserName() in /var/www/html/plugins/HeatmapSessionRecording/API.php line 577

Hi, can you please try restarting your web server, and check it for any error logs?
