The previous download methods have the vsix signatures verified by the Marketplace, but for this method, you can do the verification by downloading the matching manifest and signature.p7s file and running npx @vscode/vsce@latest verify-signature -i <.vsix> -m <.signature.manifest> -s <.signature.p7s> vscode-vsce#1044.
