promise - how to hit other microservices from a common endpoint in R plumber

Question

Suppose I have 3 microservices named as app1, app2 and total. app1 runs on port 5001 and takes two parameters x and y -> endpoint = localhost:5001/app1?x=1&x=2

app2 runs on port 5002 and takes one parameters a -> endpoint = localhost:5001/app2?a=1

Now there is 3rd endpoint which is dependent on both the microservices (app1 and app2) and the common endpoint is localhost/5000/app?x=1&x=2&a=1.

Now with the help of plumber R package, I want to trigger app1 and app2 both whenever app is triggered.

Please help me by telling how I can achieve that?
