Conversion of const char** to std::vector<const char *>

I am currently working on a Vulkan project that uses the glfw library for window handling.

To get the required extensions glfw provides const char** glfwGetRequiredInstanceExtensions(uint32_t *count).

To avoid passing around a const char** together with the count i wrote a simple helper function that converts the const char** to a std::vector<const char *>:

std::vector<const char *> GetRequiredInstanceExtensions()
{
    uint32_t extensionCount = 0;
    auto extensions = glfwGetRequiredInstanceExtensions(&extensionCount);

    return std::vector<const char *>(extensions, extensions + extensionCount);
}

I am not sure how this works memory wise. From what i understand the data gets copied into the vector here. I am not sure if i have to clean up the const** that gets returned from glfwGetRequiredInstanceExtensions and if it's fine to use a std::vector<const char *> in general. The vector is just cleaning up the pointers and not the whole c-strings when it goes out of scope if i am not mistaken.

Do i have memory leaks here?
