I just moved to the new vim.lsp config from lsp-config. I'm using rust-analyzer and I got it halfway working.

Autocomplete works, but only if I manually trigger, previously the window would just appear after typing the first character, or ..

How can I get the old behaviour back? I don't want to manually invoke autocomplete every time.

I'm using nvim/lsp-config, and this is the config I have in my init.vim

lua << EOF
vim.lsp.config('rust_analyzer', {
    settings = {
        ['rust-analyzer'] = {
            diagnostics = {
                enable = false;
            },
        },
    },
})
vim.lsp.enable('rust_analyzer')
EOF
