Shell Script :: How to put multiple filter in grep command

My current script is returning "userAccessId" value for all the blocks under "useraccesses". Below i have written the script and backend json response. I have filtered and getting "userAccessId" value for all the blocks under "useraccesses".

But my actual requirement is, i want to get "userAccessId" value whose "numberOfAccessSchedules" value are greater than zero. Can someone please modify my script.

MyScript.sh

#!/bin/sh
#

export TOKEN=$(curl -k -s -d "client_id=guard-public" -d "grant_type=password" -d "username=test" -d "password=test@123" "https://10.00.00.00/auth/realms/guard/protocol/openid-connect/token" | python -c "import sys, json; print json.load(sys.stdin)['access_token']")
    
#GET UserAccess ID

#echo "GET useraccess ID for all users"

curl -k --location --request GET "https://10.00.00.00:111/guardian-restservice/v1/useraccesses?page=$i&page_size=10000" -k -H "Authorization: bearer $TOKEN" | jq | grep "userAccessId" | awk -F : {'print $2'} | sed 's/,//' >> alluseraccessId.txt

Backend JSON Response without filter

{
  "page": {
    "currentPage": 1,
    "totalPages": 7,
    "pageSize": 10000
  },
  "useraccesses": [
    {
      "userAccessId": 918568786,
      "numberOfAccessSchedules": 2,
      "customAttributes": {},
      "networkElementUserId": ""
    },
    {
      "userAccessId": 918569013,
      "numberOfAccessSchedules": 1,
      "customAttributes": {},
      "networkElementUserId": ""
    },
    {
      "userAccessId": 918569301,
      "numberOfAccessSchedules": 0,
      "customAttributes": {},
      "networkElementUserId": ""
    },
    ...........
    ...........
    ...........
   ]
}

Current O/P (alluseraccessId.txt)

918568786
918569013
918569301

Expected O/P (alluseraccessId.txt)

You can easily extract the values you need with jq, the de facto standard utility for working with JSON in shell scripts. Trying to apply regular expression based tools to structured data formats like JSON or XML is almost always a bad idea.

curl ... | jq '.useraccesses[] | select(.numberOfAccessSchedules>0) | .userAccessId' >> alluseraccessId.txt

Adds

918568786
918569013

to the file.

Means 'for each element of the array in the useraccesses element of the top level object, if its numberOfAccessSchedules element is greater than 0, print the value of its userAccessId element.'
