Issue Plesk server primary domain Google Workspace

Server operating system version

CloudLinux 8.9

Plesk version and microupdate number

18.0.60 Update #1

Hey, after turning on Google Workspace email for primary domain on Plesk and selecting Disabled for incoming mail webmail stopped working. I see default plesk page. That's very inconvenient because subscription users on that server use that webmail to read their messages (I know they can use webmail.clientdomain.com, but somehow they get used to use plesk primary domain, maybe because other services are set in that domain too... like ftp, whmcs etc).

How to force webmail to work on primary domain with disabled for incoming mail? Webmail is Roundcube

webserver is LiteSpeed Enterprise (just in case it's important)
