How to initialize a vector of shared_ptr for classes that take one parameter?

The following is the expanded version, which works fine, only I'd like to use an initializer list

vector<shared_ptr<Foo>> inputs = {
    make_shared<Foo>("foo"),
    make_shared<Foo>("bar"),
    make_shared<Foo>("baz")
};

So I've tried something like

vector<shared_ptr<Foo>> inputs2 = {
    { "foo" },
    { "bar" },
    { "baz" }
};

as well as with two brackets, or none, ie {{ "foo" }} and just "foo".

std::shared_ptr<Foo> foo = { "foo" };

doesn't compile either, so I think this isn't a matter of vectors at all, but initializing shared_ptrs with initializer lists.
