I have the two below LAMBDA functions

=LAMBDA(z,filter(z,index(z,,17)=max(index(z,,17))))(IMPORTRANGE("1l_xGjh4YNCANLg-npQWzlXXpQJ3nidC4RzBvR62efuE", "Overview!A2:Z"))

=LAMBDA(z,filter(z,index(z,,12)=max(index(z,,12))))(IMPORTRANGE("1madkVso_zaoU9MH2gvtVlTaT2iJ9nMcCxS8ux0Vpz14", "Overview!A2:Z"))

How can I combine them to ensure the data is stacked on top of each other/appended? I know you can use QUERY but I am reluctant to use this because one column in my dataset is of hyperlink format and QUERY would just import it as a string (and hence wouldn't be clickable).

I tried the below curly brackets format but it doesn't work (error message is "an Array Literal is missing values"):

={(LAMBDA(z,filter(z,index(z,,17)=max(index(z,,17))))(IMPORTRANGE("1l_xGjh4YNCANLg-npQWzlXXpQJ3nidC4RzBvR62efuE", "Overview!A2:Z")));(LAMBDA(z,filter(z,index(z,,12)=max(index(z,,12))))(IMPORTRANGE("1madkVso_zaoU9MH2gvtVlTaT2iJ9nMcCxS8ux0Vpz14", "Overview!A2:Z")))}
