Scan through files having xml format but not with unsupported extension

Hi, I am new to Sonarqube (less than a week). Could you let me know if it is possible to scan / analyse files having xml format but with unsupported file extensions? I want to scan through the following file extensions. Is it possible to do so?

.pega
.pAutomation
.pTests
.pegaProject

list goes…

I am getting ‘indexed with no language’ in the trace file when using SonarQubeAnalyze@5 task in Azure devops pipeline. Could you help? Thanks.

You can adjust the file suffixes associated with XML files as documented here.
