WebTunnel memory requirement is not mentioned on the list of requirements

Possibly number of people are running low end VPS with lets say 512-1024MB RAM where portion of that memory is already used so it would be good to know how much memory is roughly needed to run the WebTunnel, maybe at https://gitlab.torproject.org/tpo/web/community/-/edit/main/content/relay/setup/webtunnel-bridge/contents.lr (under "The requirements for deploying a WebTunnel bridge are:")
