This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 覛 is uncertain. It visually contains 見 (see) on the right, but the left component's origin and the character's original meaning are unclear.
Since the meaning is uncertain, focus on the shape: 見 (see) on the right suggests something related to looking, but the left part is obscure.
For ベキ, imagine a beckoning gesture to look closer: beck -> ベキ, and the 見 component hints at seeing.
