Created webhook in another store (using API) doesn't trigger any data ??

Hello,

I have created a webhook using Shopify API for a store for updating the products and I have a partner account access of it https://prnt.sc/LErQSChJ0a2I

But I haven’t getting any data from webhook for above store.

Furthermore I have created the same webhook for other test store (with full access) and it works fine and data is triggered from there and products are updated successfully https://prnt.sc/c5N7e_iqNUiV

Can some one confirm- If the delegate access to above store and permission is not given to notification/webhook so can this be the issue ?

Also is it required to install the app for triggering the webhooks which I think is not necessary because same is working on test store without installing the app and using just the Shopify APIs.

Thanks!
