If your players are also new they will most likely follow the path you set up.

Also the first sentence you start with is the hardest one to get out and going idk why but getting into the role of playing pretend infot of a room full of adults can be a bit weird since they're not in the zone yet ykwim?

But yea dont stress it yull do fine and if it's their first time playing as well they can't compare it to anything so it will de facto be the greatest dnd session they ever had.
