Azure Logic Apps - Is there a separate library/api to instantiate functions in expressions? - azure-logic-apps

Question

May I know if there is a separate library/api of azure logic app that we could use to instantiate functions in expressions?
We're using logic app for scheduling in our products, and would love to keep the same expression resolving behavior beyond scheduling scenario.
Below is an example to demonstrate two scenarios, and my question is not limited to the function itself.
scheduling scenario: in below workflow, we use function #addToTime(#utcNow(), 1, 'Day') for scheduling HTTP request.
single request without logic app: we have to implement the function resolving logic from scratch. This also makes the two scenarios different.
{
'location': '{LogicAppRegion}',
'properties': {
'state': '{LogicAppState}',
'definition': {
'$schema': 'https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#',
'actions': {
'HTTP': {
'inputs': {
'body': {"ParameterAssignments": {"time": "#addToTime(#utcNow(), 1, 'Day')"}},
'method': 'POST',
'uri': '{LogicAppUri}'
},
'runAfter': { },
'type': 'Http'
}
},
'contentVersion': '1.0.0.0',
'outputs': { },
'triggers': {
'Recurrence': {
'recurrence': {recurrence},
'type': 'Recurrence'
}
}
}
}
}
Thanks in advance for your help!

Here is one of the workarounds that you can try.
I have added Recurrence connector and then used a HTTP action connector instead of HTTP request trigger this helped to satisfy both the requirements
{
"definition": {
"$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
"actions": {
"HTTP": {
"inputs": {
"method": "POST",
"uri": "<Your Required URI>"
},
"runAfter": {},
"type": "Http"
}
},
"contentVersion": "1.0.0.0",
"outputs": {},
"parameters": {},
"triggers": {
"Recurrence": {
"recurrence": {
"frequency": "Day",
"interval": 3
},
"type": "Recurrence"
}
}
},
"parameters": {}
}
