Using home-manager to subscribe to more folders in Thunderbird

I have my email account set up like this:

  accounts.email.accounts = {
    "<address>" = defaults // {
      primary = true;
      address = "<address>";
      userName = "<address>";
      passwordCommand = "pass <address>";
      imap.host = "...";
      imap.port = 993;
      smtp.host = "...";
      smtp.port = 25;
    };

When I run home-manager switch, the account appears correctly in Thunderbird, but in order to access the gitlab folder, I have to manually use the Subscribe functionality inside of Thunderbird. Is there some way to subscribe to this folder via home.nix?
