workflow – Microsoft flow using IF with OR

I need to add a if declaration to an email:

if (is equal to (body (& # 39; Aktualizuj_element_2 & # 39;)?)?['Typ_x0020_urlopu']?['Value'], "Badania lekarskie", "Inne", a body ("Aktualizuj_element_2")?['Typ_x0020_urlopu']?['Value'])

This if works correctly.

Now, I need to convert that if and add OR, then I added:

if ((is equal to (body (& # 39; Aktualizuj_element_2 & # 39;)?)?['Typ_x0020_urlopu']?['Value'], & # 39; Badania lekarskie & # 39;) or (is equal to (body (& # 39; Aktualizuj_element_2 & # 39;)?)?['Typ_x0020_urlopu']?['Value'], "Inna nieobecność (kod 350)", "Inne", the body ("Aktualizuj_element_2")?['Typ_x0020_urlopu']?['Value'])

But the flows make me alert:

the expression is incorrect

How can I use OR in one IF declaration?
