Update column when jsonb array contains one of multiple values

I have a column within a table of data type jsonb and another column of type bool.

I am looking to update the latter to true, else false, when the jsonb contains a value other than 'null' for certain attributes.

This is what I have so far.

update table 
set bool_column =
case
when
        jsonb_column->'term1' != 'null' 
    or jsonb_column->'term2' != 'null'
    or jsonb_column->'term3' != 'null'
    or jsonb_column->'term4' != 'null'
then true
else false;

I was able to figure out how to select the columns in the table but I can't figure out how to update a different column.

Your help would be much appreciated. Thanks.
