I have added a new document library to my sharepoint online team site. and when i access the document library on Modern Experience, i will get this :-
which will render the documents using the List view. and i can change the List view to Tiles as follow:-
but my question is how i can set the defualt view for my document library to be Tiles instead of List? and if this can be achieved, then if i add this document library inside a modern page using the modern document library(preview) web part, will the document library get rendered in Tiles view inside the modern page?
