How can I "Find and Replace" specific characters inside TAGS using ATOM?

I need help replace the - inside my alt tags only (not the rest of the code/html).

bad: alt="Tumble-drying-allowed"

good: alt="Tumble drying allowed"

I'm using ATOM and the REGEXP tutorials are foreign to me. (so weird to look at)

Any help would be greatly appreciated.

<td data-colname="File"><strong><img title="Tumble-drying-allowed"src="wp-content/uploads/2022/01/Tumble-drying-allowed.svg"alt="Tumble-drying-allowed" width="31.18" height="31.48" />Tumble-drying-allowed</strong>File name:Tumble-drying-allowed.svg</td>

Eventually I'll target the title tag too, but I need a head start
