Reused Password

I have received information regarding one or more passwords being released on the dark web. They are old passwords that to the best of my knowledge are not used by me anymore.

I thought I would check my Proton Pass to see if there were any still in use only to find that there is no search function for this.

I know that if I found any duplicate passwords in use Pass would highlight the matter.

Would a search facility for passwords that have been highlighted as being exposed be possible?
