You can create a virtual field in the Field calculator for the grid layer and fill it with

aggregate( layer:='Your pointlayername',   aggregate:=' concatenate'='concatenate',   expression:=to_string(attributes()['attributenameofpointlayer']),  filter:=intersects($geometry, geometry(@parent)),  concatenator:=',' )

You may need to transform coordinates with function transformtransform() if grid (polygon) and coordinates points do not match due to difference for the projection
