url alias

good morning
for have more wordpress i have buy a godaddy host ( godaddy deluxe where i can connect 1 domain and more domain alias to my application )

with this hosting i can link more wordpress application to my register domain

normally if i have for example a domain mamed mydomaincom
i install wordpress in a subfolder named wordpress
so i have word press url in
https://mydomain.com/wordpress

can i create for it an “url alias”
for reach it in
https://www.mydomain.com

is this a problem of networkink ( example dsn of domain)
or a wordpress configuration
or together

and if it is possible how can i do for obtain ?
