Get value from another table Power BI

Question

I have two tables like -

Table A -

Seller	Value	Crawl_date
Mat	2	28-Aril-2023
Harry	32	28-Aril-2023
cat	0	28-Aril-2023
Jon		28-Aril-2023
Sohan	121	28-Aril-2023
Ray	3223	28-Aril-2023
Mat	2	26-Aril-2023
Harry	32	26-Aril-2023
cat	0	26-Aril-2023
Jon		26-Aril-2023
Sohan	121	26-Aril-2023
Ray	3223	26-Aril-2023

Table B-

Seller
Mat
Harry
cat
Jon
Om

My expected output would be, to create a new column for table B called "check" and assign True or 1 if the same seller is in A and if its value is greater than 0 and it should be based on the latest crawl date.

Table B -

Seller	Check
Mat	True
Harry	True
cat	False
Jon	False
Om	False

UPDATED REQUIREMENTS

Check = 
VAR x = SELECTCOLUMNS( TOPN(1, FILTER('Table A', 'Table A'[Seller] = 'Table B'[Seller]), CALCULATE(MAX('Table A'[Crawl_date])), DESC) ,"@y", 'Table A'[Value])
RETURN IF(x > 0 , TRUE(), FALSE())

Add a calculated column as follows:

Check = 
VAR x = LOOKUPVALUE('Table A'[Value], 'Table A'[Seller], 'Table B'[Seller])
RETURN IF(x > 0 , TRUE(), FALSE())
