Reload/Re Query jQuery Object based on Snapshot

How can I refresh or reload the state of a jQuery Object? I did some research and found these answers, but they no longer work due to a property deprecation:

How can I refresh a stored and snapshotted jquery selector variable

This worked based on this https://api.jquery.com/selector/, but it'll be removed as of jQuery 3.

how to refresh objects when i modify the HTML in jquery?

This has some related title, but it's not what I'm looking for.

These are some tests I've been doing:

//Old working solution
$.fn.refresh = function() {
    return $(this.selector);
};


$.fn.refresh = function() {
        var curr = $(this);

        window.console.log(this);
        //window.console.log(curr);
        //window.console.log(curr[0]);

        //return $(this);

        if(curr.length < 1)
            return $();
        curr = $(curr[0]);
        
        if(curr.prop('id') != '')
            return $('#' + curr.prop('id'));
        
        if(curr.prop('name') != '')
            return $('name=["' + curr.prop('name') + '"]');
    };
