Hamburger Menu

I’m basically a novice at WordPress but have blundered my way through (mostly by trial and error) to create a website for a service group:.

The hamburger menu (NAV menu?) in both desktop mode and mobile phone mode is on the right side of the screen. However, when one clicks on the menu, the pop-up menu (or drop-down menu?) appears on the left side of the screen. How can I make the menu drop down on the right side of the screen? I’m using www.remarpro.com theme Twenty Twenty-One. Is there a setting under Appearance/Customize/Nav options that will move the menu to the right? Or can someone suggest some simple CSS code that will do the trick?
