Unable to clone Private Git Repo in VS Code Remote Container - visual-studio-code

Question

I have a VM running RedHat 8.6, which is running multiple LXC containers, each with Ubuntu 22.04 installed.
The RedHat VM is used as a SSH proxy to get to the LXC Containers. There are approx 10 developers in my team, each developer has their own LXC Container.
An example VS Code SSH Configuration is as follows
IdentityFile c:\users\simon.carr2\.ssh\id_ed25519
Host jump-box
HostName 10.15.236.74
IdentityFile c:\users\simon.carr2\.ssh\id_ed25519
User bob
Host container
HostName 10.36.165.29
User bob
IdentityFile c:\users\simon.carr2\.ssh\id_ed25519
ProxyCommand ssh -q -W %h:%p jump-box
I can connect to the Host called container (which is proxied through jump-box)
Once connected, in VSCode, I try to Clone Repository in Container Volume
When prompted I put the https link to my on-prem private repo (Running in GitLab)
But I am given the following error in the terminal

How do I get VSCode to prompt me for Git Credentials?
