Change the direction of Opening the Sub-Sub Menu in WordPress?

I was making a WordPress website and all of a sudden I ran into a problem Like I have a menu at the top and there link called "More Pages" and in it, there is a link called "useful links" and when you hover over that it has it’s own sublinks (So it is a three-layer deep menu the problem comes at useful links When I hover over that, the links inside it are opening at the right side thus going out of the page and I am unable to see them) So can anyone tell me how do I make the "useful links" submenu to open on left Side So I can see them. I am Using Astra Theme In the above image you can see the useful links are opening on the right Side I want it to open on left side

Help is highly appreciated Thanks
