Deciphering/recognizing gradient to replicate them
Hello everyone and thanks to those who would like to participate in the discussion and help me learn.
I am trying to replicate an effect present on a graphic element extracted from a PDF; I don't know if it is a gradient, a glow, a blur therefore I can't replicate the object in all its features.
Surely an insider will understand at first glance what is present on the exterior in a shaded burgundy of the element depicted in the next image:

Thanks to “edit PDF” I was able to extract all the different components of the element (via Acrobat Pro's context menu it gives me the option to edit the element using Illustrator). So I know that gradients have been applied but I don't know what kind they are and how they were obtained. Basically I have extracted burgundy filled rectangles with 30% opacity that have the geometric shape of the element inside them with very ill-defined/blurred white outlines.
If they are superimposed on the geometric shape they generate the gradient I am trying to replicate.
Forgive me if what I just wrote comes across as very confusing and is not described using appropriate language but I hope the image is more explanatory.
In any case, I also attach a screenshot of the elements extracted in Illustrator

Thank a lot to all the community members will spend their time to help me
