Error in configuring Moodle LTI 1.3

My moodle is installed in a folder (moodle) and the url is something like this https://host/moodle

When I configure the activity using the LTI external tool everything seems to be ok but when I open the activity the actual redirected URL is https://host/mod/lti/auth.php, without the moodle folder (the expected URL is https://host/moodle/mod/lti/auth.php). Am I missing something? Or is my configuration not supported and Zoom LTI wants Moodle to be installed in the domain root?

Best regards

Massimo
