Neo4j Desktop on Ubuntu 20.04 - no apps

Hi everyone,

I was browsing through the possible answers to my issue, but no one matches it.

Issue: I do not see the apps in the Neo4j Desktop. I installed this app on two different machines (same OS), but in one of them (in the one I cannot see the apps) I am behind a firewall and I am sure I need to configure this firewall to enable the apps.

Question: What are the ports and URLs to enable the apps? I would like to install Grandstack (GraphQL, Apollo and React integrated Neo4j - node.js), for example, but without apps in Neo4j Desktop app, I could not find any documentation on how I can install it.

Can anyone help me, please?
