This is one of the reasons I am a really, really big fan of Google Cloud's Task Queues. It allows the stupidest, simplest temporal execution of HTTP invocations.

Currently working on a project in AWS and it's stunning how complicated it is to achieve the same simple need of "I want to execute this HTTP call at this time in the future". It's either AmazonMQ -- using either ActiveMQ or RabbitMQ with plugins -- or hacking around SQS's 15 minute delay limit. In our case, we are going to end up wrapping our messages in an envelope with a delivery time and if it hasn't met the delivery time, we put it back into SQS.

GCP is highly underrated for how it simplifies control over execution of code. Pub/Sub and Task Queues both have HTTP delivery built in. Couple that with Google Cloud Run and it is a recipe for building almost any type of execution model with much less complexity and overhead

In case you want to avoid an extra envelope, you can also add custom headers to SQS messages. This can be handy if you want to implement that delay hack without parsing message bodies.
