DocumentRoot equivalent in OTD

Hi Experts,

My customer has been provisioned JCS 12.2.1.3 with OTD.

Their on-premises implementation uses OHS where they implemented the following directives for serving Angular application pages:

httpd.conf

---------------

DocumentRoot "${ORACLE_INSTANCE}/config/fmwconfig/components/${COMPONENT_TYPE}/instances/${COMPONENT_NAME}/htdocs"

<Directory "${ORACLE_INSTANCE}/config/fmwconfig/components/${COMPONENT_TYPE}/instances/${COMPONENT_NAME}/htdocs">

pos.conf

------------

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d

RewriteRule ^ - [L]

# If the requested resource doesn't exist, use index.html

RewriteRule ^ /index.html

The objective here is to resemble what exist in OHS configuration files in OTD.

Any idea will be highly appreciated.
