vRA API REST call get more then 20 items

I can't figure out how to get the API call for entitledCatalogItems to return more then 20 items

(powershell)

$vRAURI = "https://vcac"

$login=""|Select username, password, tenant

$login.username = "login"

$login.password = "passwd"

$login.tenant = "tenant"

#auth

if(!$ApiToken) { $ApiToken = Invoke-RestMethod -Method Post -uri "$($vRAURI)/identity/api/tokens" -Body (ConvertTo-Json $login) -ContentType "application/json"}

#List Shared and Private Catalog Items

$entitledCatalogItems = Invoke-RestMethod -Method Get -uri "$($vRAURI)/catalog-service/api/consumer/entitledCatalogItems" -Headers @{"Authorization"="Bearer $($ApiToken.id)"}  -ContentType "application/json"

$entitledCatalogItems.metadata

size          : 20

totalElements : 22

totalPages    : 2

number        : 1

offset        : 0

From the API doc from the URL above, it's not showing any parameters to pass to query the next page
