Unable to use OR operator with mobileby xpath

poster = Find(
    by=MobileBy.XPATH,
    value='//XCUIElementTypeCollectionView/XCUIElementTypeCell'
          '/XCUIElementTypeOther/XCUIElementTypeImage |'
          '//XCUIElementTypeCollectionView/XCUIElementTypeCell[1]'
          '/XCUIElementTypeOther/XCUIElementTypeImage')

The element I’m finding has either one of the xpaths above and I’m using the or operator but it seems it’s not supported, how can I fix this? There are no accessibility id’s available.

“TypeError: unsupported operand type(s) for |: ‘str’ and ‘str’”
