review schema for a review article

Dear Rankmath Support team

Could you please help in solving Review snippetserrors that caused by the google search console for my review article in this URL: https://hearinghealthguide.com/tinnitus-911-review/

I got three types of errors:

1. Invalid Object type for field “itemReviewed”:
and here is the code that causes the error:

“aggregateRating”: {
“@type”: “AggregateRating”,
“ratingValue”: “5.0”,
“reviewCount”: “35”
},

2. Item does not support reviews,

and here is the code that causes the error:

“review”: {
“@type”: “Review”,
“datePublished”: “2021-05-29GMT+000012:10:47+00:00”,
“dateModified”: “2022-03-13GMT+000006:55:11+00:00”,
“author”: {
“@type”: “Person”,
“name”: “admin”
},
“reviewRating”: {
“@type”: “Rating”,
“ratingValue”: “4.7”
}
},

Please refer to the attached screenshot :
