vscode-langservers-extracted | vscode-langservers bin collection | GCP library

In bash, I would run

(npm install -g npm@latest && npm install -g neovim bash-language-server vscode-langservers-extracted graphql -language-service-cli solidity-language-server typescript-language-server)& to install some packages I need.

I have been trying to do the same command in fish and am having trouble. I am thinking of creating a separate file and run it with bash, but would be nice how to do this in fish. I am getting a fish: Command substitutions not allowed error. I can run this

npm install -g npm@latest && npm install -g neovim bash-language-server vscode-langservers-extracted graphql -language-service-cli solidity-language-server typescript-language-server, but it is not async. I have a bunch of other commands like this, hence async would be faster

Thanks
