Next.js (or node.js) app installation

i have a next.js application (it could run with node.js to) and need to deploy it on the server
but i have used nginx only option (dosent install apache) and cant use Web Template NGINX
i have followed this link GitHub - JLFdzDev/hestiacp-nodejs: HestiaCP-NodeJS | This plugin allow install multiple nodejs apps using HestiaCP but after installetion finished i cant find the config files in panel
so i have copied Nodejs.tpl and Nodejs.stpl to php-fpm folder and its showed in panel
after saving it and deploying app in private/nodeapp/ when opening the domain it showed Page Not Found error

is there any easy way to deploy next.js or node.js apps in hestiaCP?
