No adhesive recommended for underlayment. You will thank me later. Install as cndamm suggested would be best.
Any free advice given is worth double price paid.

Subfloor adhesive is for subfloor sheathing not for underlayment . As posted the underlayment is either nailed down with hand nails made specifically for this or pneumatic staple guns using 1/4" x 1" staples on 6" centers both on seams and the field.
You want to be able to remove old flooring with underlayment in the distant future, hence no adhesive.

I use rosin paper or 15 pound felt between the 2 layers helps with squeaking

I use ring-shank nails. Lots of them, spaced every 6 to 8 inches. No glue. Never done staples but I know it's an acceptable method.

Just about every component of a home should be installed with the understanding it may eventually need to be removed without too much damage to the home.

Having taken up a layer of underlayment that I meticulously installed decades ago with ring shanked nails on a 6" grid...I might suggest not using construction adhesive...any more difficult to remove than that might involve incendiary assistance...

Nail it down. Don't forget to use a latex primer on your underlayment. It's cheap and goes on easy and will greatly aid with adhesion.
