HTML embed within link blocks are not linked(not clickable)

Please help embed a Vimeo video within the link block!
I tried to add an HTML embed to put Vimeo videos as thumbnails with other text blocks. However, the text blocks within the link blocks were linked(clickable), while HTML embed blocks within the same link blocks were not linked(not clickable).

I tried to add custom code but did not work.
I tried to replace HTML embed with Background Video component, but it didn’t work too.
How can I solve this?
