Use embed image and then you’ll be able to access the SVG elements to style them how you want. You don’t want it going into the image management as then it’s fixed as is (you could use tinting, but it’s super dodgy)
It looks like you imported the SVG into the image management tool, and then used an image component to display it. The way I did it actually skips that step entirely.
You’ll want to drag the SVG from Windows Explorer directly into your view. You should then have the ‘Save and link’ and ‘Embed image’ options shown in my post. If you pick Embed image you should have access to the individual SVG elements.
For reference, ‘Save and link’ basically does what you’re seeing (and what my original post showed) - it inserts the image component which references the SVG file, rather than inserting a drawing component which lets you manipulate the SVG directly.
