Start-Process not work in vscode remote-ssh

Question

I use vscode remote-ssh to use my windows10 system. And I use the following command for a background process.

Start-Process -WindowStyle hidden -FilePath "webui-user.bat"

Then I close my vscode. And the process keep running for 5 minutes. Howerver, I's closed after 5 minutes. Can Anyone suggest me a solution for a background process.
