Rockfall windshield, how and where repair?

Moin Moin! My XC90 got a scratch on the glasses. It’s a 2mm impact and the disc is torn on both sides of it about 6mm each. (only the outer) Now my question: Where and how would you have it repaired? There are alternative possibilities, (e.g. a repair with resin on discsDoctor,CarGlas & Co.) or let the disc completely replace, e.g. at the . If you have the defect repaired, this takes over without own participation the partial cascade. However, the thick elk is leased and one has to have repairs carried out, if I am not mistaken, by a specialist workshop. Does this also apply in such a case or could one have the disc changed elsewhere, which would then possibly also be made own part-free there. Greeting Frank!
