Re-importing the logo and settings to the theme

I completely removed the logo and all logo settings from the header. I tried to replace the logo by placing it in the header as a normal image, but it doesn’t scale responsively. Is there any way to restore the original logo with placing and settings? I can’t “cancel” to any older version, but the correction should be done for this now afterwards. I have a free version of the theme in use. Thanks if someone could help. If necessary, I will share the url here.
