Assalamualaikum, if i was in my last rakah and i didnt touch nose in final sujood, i got up for tashahhud and the moment i realised i went and added another rakah because i thotught it would be invalid and did sujus as sahw , if this is wrong do i need to repeat the prayer?

Ustadh AbdulAziz al-Haqqan

Don't repeat the prayer and don't repeat this again
