Minim and Hifi Cast - Show Composer

[Anna Count]

I use Minim Server with Hifi Cast Premium. I cannot make Composer show in Now Playing in Hifi Cast. They suggested adding Composer.displayRole={artist} to the tagCustom in Minim. I have tried that but just get a message "incorrect tag name Composer in property tagCustom" in Minim which will not start until this is removed

Is there any way I can get composer to show in Now playing please?

Thanks
Anna
