Hi Azharul Islam Anik, SlieveCroob is no longer on the team so I will be handling this on their behalf. thanks for reaching out! 
I aligned and connected the service road here https://www.openstreetmap.org/node/9182675544, but did not add the wheelchair=yes tag on https://www.openstreetmap.org/way/993911773. It looks like the user Nafis Fuad Khan (https://www.openstreetmap.org/user/Nafis%20Fuad%20Khan) was the one who added the wheelchair=yes tag in this changeset https://osmcha.org/changesets/112694269. Have a good day
