TTMSFNCButton: Change TintColor of SVG (FMX not VCL)

How can I change the tintcolor of SVG in the TTMSFNCButton? FMX not VCL, and not the tintcolor of SVG in the BitmapContainer. I have already tried several things. IconTintColor does not work. I think this is an elementary function.

Sorry that's not possible, if you are using a TTMSFNCBitmapContainer, then you need to change the tint color in the bitmap you added there, if you want to have a unique fnc button tint color, you'll need to add a bitmap via the Bitmap property, and then change the tincolor via:

TMSFNCButton1.Bitmap.SVG.TintColor := gcRed;
