Show filter button by default

Is it possible to show the filter button (which results in the right hand fly out menu) by default?

I think the answer is "no not in the standard sharepoint experience", but what if the list was migrated into PowerApps or something, could a filter menu be displayed so its more obvious to users?

I have a list of volunteering opportunities (with different fields) in the Gallery view, and the vast majority of people will certainly want to use the filters, so making this as obvious as possible is ideal.
