Toyota Tacoma Seat cover installation question

I've got a 2019 Tacoma and in the process of installing seat covers on the thing. The issue I have is I am unable to get to the long straps that will be in the underside of the seat so I can connect them for a tight fit.

I am basically working with 1 1/2 arms due to an injury and can't reach under the seat well, especially with all of the SRS wiring, etc. that's underneath.

I know that Coverking has a long upholstery tool that can be used to help in hooking those straps; of course I didn't get them with my seats (that's another battle). Does anyone have any ideas what can be used to make that long reach to pull those straps together, so I can finish this job?

 

remove the seats and install the covers. Takes about 5 mins to take the 4 bolts and disconnect the two plugs.
