[antoniusnaumann]

Description

As a user I want to check if my requests are accepted, denied or pending on a separate page.

Conditions of satisfaction

• in the request page, i can also see all requests i sent, that were not accepted nor denied yet

if you send a request the plus is not there anymore -> shows you send a request
if the other person denies your request the plus should be there again -> no direct sign he denied the request
