Tracy and Latte with PHP7.2

I have to dev it on PHP7.2.3.
So I install Tracy 2.9.8 and Latte 2.11.7 via composer.
But this follow extension does not work.

$latte->addExtension(new Latte\Bridges\Tracy\TracyExtension);

The code work in Tracy last ver. with PHP8.1
Is there a way to debug a latte with old Tracy and Latte?
