[Feature] Option to show return type in virtual text

[ofirgall]

Hey, I'm using the plugin only with virtual text to achieve a minimal view of the current argument like so:

I would like to be able to configure the plugin to add a virtual text for the return type too, is it possible?

Btw this my cfg:

local lsp_signature_cfg = {
    bind = true,
    use_lspsaga = false,
    doc_lines = 0,
    floating_window = false,
    hint_scheme = 'LspSignatureHintVirtualText',
    hint_prefix = ' ',
}

The Lsp does not specify the return type in its response. So it is possible but requires some efforts. Also, it may differ from language to language.

Doesn't the floating window shows the return type?

The floating shows the function definition. So it requires a parser to get the return type.
