External testing

Good afternoon, I have encountered a problem that I do not have the opportunity to select a build for external testing, but I can test the application through internal testing. How can we make testFlight let me choose the build I currently have?

Ensure your the build is uploaded using the 'TestFlight & App Store' distribution method.
