Problem in onesignalsender extension

I am designing an application through which the user can send his orders and this data will be recorded in airtable.
On the other hand, the admin receives these orders in another application of his own in cardview. I used it onesignalsender to get notification in admin app after user send his order… It worked only once and did not work again
This is the users app block

And this is the admin app block
