Hide SharePoint bar when clicking a button that tries to execute a flow

Hello Dear Community,

I have created a list of processes for work where there are several process steps that need to be completed. I have created a button called “Next” that executes a Power Automate flow when clicked. The flow is also running so far, but now I have a problem with a bar that is very annoying (Screenshot)

Is there a way to hide the bar so that the flow is executed directly when the button is clicked on?

Thank you very much
