Update a single input block value from a modal

[nassim-kachroud]

Hi!
Is there any way to update a single input text from a modal after a selection from another field (select)?
I have the following code:

case slack.InteractionTypeBlockActions:
	// This is a block action, so we need to handle it
	for _, action := range interaction.ActionCallback.BlockActions {
		if action.ActionID == "incidentStatus" {
                        updatedStatusMessage := site24x7.GetDefaultStatusMessage(site24x7.IncidentStatus(selectedIncidentStatusIndex))
                        // TRYING TO DO STUFF HERE
			currentBlocks := createSite24x7ModalRequest.Blocks
			blocks, _ := interaction.View.Blocks.MarshalJSON()

			for _, block := range currentBlocks {
				if block.(slack.InputBlock).BlockID == "incidentStatus" {
					// createSite24x7ModalRequest.Blocks.BlockSet = currentBlocks
                                         // BELOW IS THE ONLY CHANGE I WANT TO DO ON THE WHOLE MODAL
					// createSite24x7ModalRequest.Blocks.BlockSet[i].(slack.InputBlock).Element.(slack.PlainTextInputBlockElement).InitialValue = updatedStatusMessage
					// currentBlocks[i].(slack.InputBlock).(PlainTextInputBlockElement)
				}
			}
		}
                // Need to pass the updated Request
		client.UpdateView(createSite24x7ModalRequest, createSite24x7ModalExternalID, createSite24x7ModalHash, createSite24x7ModalID)
	}

Thanks a lot!
