How to upload many files in azurerm_function_app_function

i can upload this file :
file {
name = “run.csx”
content = file(“./run.csx”)
}
but if i want more, so second file will be same the first for the content

so how can you upload many files in resource “azurerm_function_app_function”

my funApp.tf :
resource “random_string” “uni_nam” {
length = 8
special = false
upper = false
}

resource “azurerm_windows_function_app” “win_fun_app” {

fun. have to a unique name & available

name = “{var.fun_app_nam}-{random_string.uni_nam.result}”
resource_group_name = azurerm_resource_group.rg_lab.name
location = var.location

storage_account_name = azurerm_storage_account.sto_acc.name
storage_account_access_key = azurerm_storage_account.sto_acc.primary_access_key
service_plan_id = azurerm_service_plan.svc_pla.id

site_config {
application_stack {
dotnet_version = var.fun_app_dot_ver
}
}

app_settings = {
“APPINSIGHTS_INSTRUMENTATIONKEY” = “azurerm_application_insights.app_ins.instrumentation_key”
}

depends_on = [
azurerm_application_insights.app_ins
]
}

resource “azurerm_function_app_function” “httpTrigger” {
name = var.appFun_fun_name
function_app_id = azurerm_windows_function_app.win_fun_app.id
language = “CSharp”

Changing this forces a new resource to be created

so can’t use more that one file for contents different

e.g. readme.md & run.csx

workAround : upload_files

file {
name = “run.csx”
content = file(“./run.csx”)
}

config_json = jsonencode({
“bindings” : [
{
“authLevel” : “function”,
“name” : “req”,
“type” : “httpTrigger”,
“direction” : “in”,
“methods” : [
“get”,
“post”
]
},
{
“name” : “$return”,
“type” : “http”,
“direction” : “out”
}
]
})
}
