I have been searching everywhere for the first order GR term that describes the gravitational force of a mass.

Could someone kindly show me the term that describes this?

Look up the term "precession of the perehelion of Mercury's orbit" in any general relativity text.

The term "gravitational force" is a thorny one in general relativity, and it does not map well to the formalism of the theory, but as mentioned in the comments, the Post-Newtonian expansion is the simplest way to apply that concept.
