APIM developer portal generated sitemap contains relative path instead of absolute canonical url links
Bug description
On APIM Developer Portal, a sitemap.xml file is automatically generated which can be used for search engine indexing. Unfortunately, the sitemap does not generate full path to resources. Relative url paths are not supported by some search engines like Google (https://developers.google.com/search/docs/advanced/sitemaps/build-sitemap#general-guidelines)
Reproduction steps
After publishing the portal, the sitemap can be found in the root directory at "https://[portal host path]/sitemap.xml". Inspecting the sitemap reveals relative paths for all resources. See snippet below (screenshot):

Expected behavior
A well formatted sitemap where the each "loc" element in the "urlset > url" is rendered as an absolute canonical link of the page complete with the protocol (https://) specified. The namespace used on the generated sitemap specifies the sitemaps.org namespace. The https://www.sitemaps.org/protocol.html page describes the "loc"element as:
"URL of the page. This URL must begin with the protocol (such as http) and end with a trailing slash, if your web server requires it. This value must be less than 2,048 characters."
See sample screenshot below:

Is your portal managed or self-hosted?
Managed
Question
Does the sitemap generation have any settings which can be configured to generate full canonical url paths?
