How could I manage(add or delete) git repos on webpage by cgit?

Question

I'm using cgit as web front-end of git, showing my git repos. But I couldn't find out how to add/delete repos by cgit itself. Each time I want to create a new remote repo, I have to log in to my server, create it manually. It's so inconvenient.

I've read cgitrc.5.txt, but it seems to has no relative function. Hope that there's some easy way to add/delete/manage repos in cgit, otherwise I'm thinking about write it myself, but it may be too hard to a basic user...

Is there any way or projects to work with cgit and help managing repos? By the way, how could i find some groups of cgit users, so that I could discuss with them, not asking such a foolish question here......

Additional Information:

My cgit version is commit 09d24d7, current master branch. Global cgit config(/etc/cgitrc):

Besides, I'm using nginx to proxy the web page, below is my nginx configure relative to cgit:

server {
    listen 80;
    server_name git.mydomain.com;
    return 301 https://$server_name$request_uri;
}

server {
    server_name git.mydomain.com;
    listen 443 ssl http2;

    ssl_certificate somewhere;
    ssl_certificate_key somewhere;

    root /var/www/cgit;
    try_files $uri @cgit;
    client_max_body_size 10m;

    location @cgit {
        include fastcgi_params;

        if ($arg_service = git-receive-pack) {
            rewrite (/.*) /git_write/$1 last;
        }

        if ($uri ~ ^/.*/git-receive-pack$) {
            rewrite (/.*) /git_write/$1 last;
        }

        if ($arg_service = git-upload-pack) {

        if ($uri ~ ^/.*/git-upload-pack$) {

        }
    }

    location ~ /git_read/(.*) {
