How can I use a pop-up on the side bar?

[green-study]

I want to make a pop-up on the navbar(pc ver) and sidebar(mobile ver).
But, It only works on the navbar.
Is there any way to make it possible on the sidebar?

-- source code (docusaurus.config.js navbar) --

-- navbar --

After click the "Go to Lesssons" button

Pop-up appear

-- sidebar --

Pressing the "Go to Lessons" button does not bring up the pop-up.
When the button is pressed, "Clicked" message is displayed in the console, but the console message does not appear.
The button does not function normally.
I've also used the <button> tag instead of <a>.
