Flooring Glue

I had the dealer do some warranty work on my 2020 Jayco 26XD class C in the spring last year. They had to cut the vinyl (I think it's vinyl) flooring to get the work done. Now the vinyl flooring in the work area is coming unglued. What would be the correct glue to repair this? I'm sure it's flooring glue, but is there a special one for RV's? I did a search but couldn't seem to find a good reference. Fortunately this problem is in an area that is pretty much out of the way and nobody walks there. It's a slit about 12 inches long, both sides can be gently lifted about an inch. I looked on line too but only found 1 gallon containers. I only need a small amount..
