How to collapse the content of the sidebar in the mobile version of Wordpress?

Question

WordPress

Hello! I have a site - an article, in the sidebar there are different filters and categories, and it is very necessary that these filters be available only by clicking on some additional button. It's in the mobile version.
I searched for plugins, googled, but something sensible did not come across

If you know how to code, you can write it yourself in just a couple of lines.
1. Add a button
2. Attach an event handler to it
3. Change styles by button (let's say the block height is from 0 to 100%), or display: none to block;
