Mattermost modify message with incoming bot

Using my Mattermost bot I can remotely send a message to the channel and when the message is interacted with (Interactive messages) I can update the old message with the response to the request to my url (actions integration url).

However, I have not found a way to remotely change my message if no one interacts with the message I sent. What can I do?

I don’t want to use an API_KEY with broad permissions for this operation
